Exynos5: clock: Update the equation to calculate PLL output frequency

According to the latest exynos5 user manual, the equation for
calculating PLL output was changed to
FOUT= MDIV x FIN/(PDIV x 2^SDIV)
earlier it was
FOUT= MDIV x FIN/(PDIV x 2^(SDIV -1))
So updating the clock code accordingly.

Exynos: uart: s5p: enabling the uart tx/rx fifo

This patch enables the uart tx/rx fifo. Now that fifo is enabled,
the uart read/write functions are modfied to check the UFSTAT register
for fifo status instead of UTRSTAT (as required with fifo's enabled).
Tested by booting linux kernel. Before enabling tx/rx fifo
"Uncompressing linux" message is garbled and after enabling it is proper.

exynos: move tzpc_init to armv7/exynos

tzpc_init is common for all exynos5 boards, hence move it to
armv7/exynos so that all other boards can use it.

Also update the smdk5250 Makefile and config file.

exynos: update tzpc to make it common for exynos4 and exynos5

This requires that cpu_is_exynos4/5 should be made available before tzpc_init.
Hence this patch also makes necessary changes to have cpu_info in spl and
invokes arch_cpu_init before tzpc_init in low_level_init.S for smdk5250.

SMDK5250: Initialise and Enable DWMMC, support FDT and non-FDT

This patch enables and initialises DWMMC for SMDK5250.
Supports both FDT and non-FDT. This patch creates a new file
'exynos5-dt.c' meant for FDT support.
        exynos5-dt.c:   This file shall contain all code which supports FDT.
                        Any addition of FDT support for any module needs to be
                        added in this file.
        smdk5250.c:     This file shall contain the code which supports non-FDT.
                        version. Any addition of non-FDT support for any module
                        needs to be added in this file.
                        May be, the file smdk5250.c can be removed in near future
                        when non-FDT is not required.

The Makefile is updated to compile only one of the files
exynos5-dt.c / smdk5250.c based on FDT configuration.

NOTE:
Please note that all additions corresponding to FDT need to be added into the
file exynos5-dt.c.
At same time if non-FDT support is required then add the corresponding
updations into smdk5250.c.

MMC: DWMMC: Fix FIFO_DEPTH calculation

Current DWMMC driver used to give FIFO underrun/overrun error every 3rd time
for mmc rescan command.
In current code FIFO_DEPTH is getting calculated after reading the default FIFOTH
register and extracting the RX_WMARK bits from it i.e (RX_WMARK = FIFO_DEPTH/2 -1).
Instead of storing the correct value, we were recalculating the FIFO_DEPT each
time which is not correct.
