Subject: s5p: gpio: change gpio coding method for s5p gpio.
Old s5p gpio coding method was not clean and was not working properly
for all parts and banks. New method is clean and easy to extend.
Gpio coding mask:
0x000000ff - pin number
0x00ffff00 - bank offset
0xff000000 - part number

Subject: MMC: DWMMC: Correct the CLKDIV register value
This patch corrects the divider value written to CLKDIV register.
Since SDCLKIN is divided inside controller by the DIVRATIO value set
in the CLKSEL register, we need to use the same output clock value to
calculate the CLKDIV value.
as per user manual: cclk_in = SDCLKIN / (DIVRATIO + 1)
Input parameter to mmc_clk is changed to dwmci_host, since
we need the same to read DWMCI_CLKSEL register.
This improves the read timing values for channel 0 on SMDK5250
from 0.288sec to 0.144sec
