Exynos5: Fix rpll_sdiv to support both peach-pit and peach-pi panels
The existing setting for rpll_sdiv generates 70.5Mhz RPLL
video clock to drive 1366x768 panel on peach_pit.
This clock rate is not sufficient to drive 1920x1080 panel on peach-pi.
So, we adjust rpll_sdiv to 3 so that it generates 141Mhz pixel clock
which can drive peach-pi LCD.
This change doesn't break peach-pit LCD since 141/2=70.5Mhz, i.e FIMD
divider at IP level will get set to 1(the required divider setting
will be calculated and set by exynos_fimd_set_clock()) and hence
peach-pit LCD still works fine.

The peach boards have their SDRAM start address at 0x20000000 instead of
0x40000000 which seems common for all other exynos5 based boards. This
means the layout set in exynos5-common.h causes the kernel be loaded
more then 128MB (at 0x42000000) away from memory start which breaks
booting kernels with CONFIG_AUTO_ZRELADDR
Define a custom MEM_LAYOUT_ENV_SETTINGS for both peach boards which uses
the same offsets from start of memory as the common exynos5 settings.

number of the current page in the buffer. The page is only read
if the requested page number is not currently in the buffer. When
a block is erased, the page number is marked as invalid if the
erased page equals the one currently in the cache. However, since
a erase block consists of multiple pages, also other page numbers
could be affected.
The commands to reproduce this issue (on a written page):
> nand dump 0x800
> nand erase 0x0 0x20000
> nand dump 0x800
The second nand dump command returns the data from the buffer,
while in fact the page is erased (0xff).
Avoid the hassle to calculate whether the page is affected or not,
but set the page buffer unconditionally to invalid instead.

board/BuR/common: move I2C initialization from common part to board-specific
At this time I2C and responsible pin-mux is setup during PMIC initialziation
within common.c, this is possible because today PMIC is always connected on
I2C0.
In Future this will be changed, PMIC isn't anymore connected to bus0 in call
cases.
So we do following:
- rename enable_i2c_pin_mux0 to enable_i2c_pin_mux to be generic for enabling
pin-mux on different or more busses.
- move the call to i2c_pin_mux and i2c_init from common.c to the specific
board.c
