power: extend prefix match to regulator-name property
This patch extends pmic_bind_children prefix matching. In addition to
the node name the property regulator-name is used while trying to match
prefixes. This allows assigning different drivers to regulator nodes
named regulator@1 and regulator@10 for example.
I have discarded the idea of using other properties then regulator-name
as I do not see any benefit in using property compatible or even
regulator-compatible. Of course I am open to change this if there are
good reasons to do so.

dm: reset: have the reset-command perform a COLD reset
The DM version of do_reset has been issuing a warm-reset, which (on
some platforms keeps GPIOs and other parts of the platform active).
This may cause unintended behaviour, as calling do_reset usually
indicates a desire to reset the board/platform and not just the CPU.
This changes do_reset to always request a COLD reset.
Note that programmatic uses can still invoke a WARM reset through
reset_cpu() or using sysreset_walk().

binman: Support accessing binman tables at run time
Binman construct images consisting of multiple binary files. These files
sometimes need to know (at run timme) where their peers are located. For
example, SPL may want to know where U-Boot is located in the image, so
that it can jump to U-Boot correctly on boot.
In general the positions where the binaries end up after binman has
finished packing them cannot be known at compile time. One reason for
this is that binman does not know the size of the binaries until
everything is compiled, linked and converted to binaries with objcopy.
To make this work, we add a feature to binman which checks each binary
for symbol names starting with '_binman'. These are then decoded to figure
out which entry and property they refer to. Then binman writes the value
of this symbol into the appropriate binary. With this, the symbol will
have the correct value at run time.
Macros are used to make this easier to use. As an example, this declares
a symbol that will access the 'u-boot-spl' entry to find the 'pos' value
(i.e. the position of SPL in the image):
This converts to a symbol called '_binman_u_boot_spl_prop_pos' in any
binary that includes it. Binman then updates the value in that binary,
ensuring that it can be accessed at runtime with:

ARC: clk: introduce HSDK CGU clock driver
Synopsys HSDK clock controller generates and supplies clocks to various
controllers and peripherals within the SoC.
Each clock has assigned identifier and client device tree nodes can use
this identifier to specify the clock which they consume. All available
clocks are defined as preprocessor macros in the
dt-bindings/clock/snps,hsdk-cgu.h header and can be used in device
tree sources.
dcache_exists, icache_exists, slc_exists and ioc_exists global
variables in "arch/arc/lib/cache.c" remain uninitialized if
SoC doesn't have corresponding HW.
This happens because we use the next constructions for their
definition and initialization:
-------------------------->>---------------------
int ioc_exists __section(".data");
if (/* condition */)
ioc_exists = 1;
-------------------------->>---------------------
That's quite a non-trivial issue as one may think of it.
The point is we intentionally put those variables in ".data" section
so they might survive relocation (remember we initilaize them very early
before relocation and continue to use after reloaction). While being
non-initialized and not explicitly put in .data section they would end-up
in ".bss" section which by definition is filled with zeroes.
But since we place those variables in .data section we need to care
about their proper initialization ourselves.
Also while at it we change their type to "bool" as more appropriate.
