ARM: implement some Cortex-A9 errata workarounds

Various errata exist in the Cortex-A9 CPU, and may be worked around by
setting some bits in a CP15 diagnostic register. Add code to implement
the workarounds, enabled by new CONFIG_ options.

This code was taken from the Linux kernel, v3.8, arch/arm/mm/proc-v7.S,
and modified to remove the logic to conditionally apply the WAR (since we
know exactly which CPU we're running on given the U-Boot configuration),
and use r0 instead of r10 for consistency with the rest of U-Boot's
cpu_init_cp15().

R_ARM_ABS32 to become R_ARM_RELATIVE, which makes

I2C: S3C24X0: Bug fixes in i2c_transfer

1) Write the correct M/T Stop value to I2CSTAT after i2c write.
   According to the spec, after finish the data transmission, we should
   write a M/T Stop (I2C_MODE_MT | I2C_TXRX_ENA) to I2CSTAT instead of
   a M/R Stop (I2C_MODE_MR | I2C_TXRX_ENA).
2) Not split the write to I2CSTAT into 2 steps in i2c read.
   According to the spec, we should write the combined M/R Start value to
   I2CSTAT after setting the slave address to I2CDS
3) Fix the mistake of making an equality check to an assignment.
   In the case of I2C write with the zero-length address, while tranfering the
   data, it should be an equality check (==) instead of an assignment (=).
