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.

ARC: HSDK: Fixup DW SDIO CIU frequency to 50000000Hz
DW SDIO controller has external CIU clock divider controlled via
register in the SDIO IP. Due to its unexpected default value
(we expected it to divide by 1 but in reality it divides by 8)
SDIO IP uses wrong CIU clock (it should be 100000000Hz but actual

So increase SDIO CIU frequency from actual 12500000Hz to 50000000Hz

But mainline U-Boot and Linux has the old address and size fixed.

This patch adds a dynamic reservation of the memory zones in the device tree bootmem

To be complete, the memory zones are also added to the EFI reserved zones.
Depends on patchset "Add support for Amlogic GXL Based SBCs" at [2].

- switched the #if to if(IS_ENABLED()) to compile all code paths
- renamed function to meson_board_add_reserved_memory()
- added a mem.h header with comment
- updated all boards ft_board_setup()

- reduced preprocessor load
- kept Odroid-C2 static memory mapping as exception

that. That effectivly doubles the size of our exception table, which
is quite a waste, given that we use it mostly for debugging purposes.
Since the register saving part is actually identical, let's just convert
that macro into a function, and "bl" into it directly from the exception
