This patch intends to add a new proid for Exynos5800 which is a
variant of Exynos5420. Product id for Exynos5800 is 0x5422.
Both Exynos5420 and Exynos5800 are pin to pin compitable. This
gives us an advantage of reusing Exynos5420 clock, pinmux, memory
and other settings.

We have a new board Peach-Pi similar to Peach-Pit. Peach-Pi
differs from Peach-Pit in configuration factors like display
resolution, memory size, SoC version etc.

As per Exynos5800 UM ver 0.00 section 17.13.2.1
CONCONTROL register bit 3 [update_mode], Exynos5800 does not
support the PHY initiated update. And it is recommanded to
set this field to 1'b1 during initialization. This patch sets this bit.
Applying MC-initiated mode makes DDL tracking ON, that helps in
compensate MIF voltage variation.

Since, not every board may have all memory channels configured
and all available banks of DMC used, we wish to refactor configs
for Memory Bank size and numbers as per board memory config.
For Example, Peach-Pit has 2GB memory and will be using only 4 banks
but Peach-Pi has 3.5GB memory and will be using all 7 available
SDRAM banks.

Add a 4G configuration and choose it based on the number of banks
declared in config file. A board with 4 SDRAM banks declared (as
per CONFIG_NR_DRAM_BANKS) will end up with the 2G confiuration.

Exynos5800 IROM has a different, from 5250 and 5420, prototype of the
usb_copy() function. Luckily the earlier version did not expect any
arguments, which means the same code could be used with old and new
SoCs, the old ones just ignoring the arguments.
