[PATCH 4/5 v2] ARM: ux500: fix I2C4 clock bit

[PATCH 4/5 v2] ARM: ux500: fix I2C4 clock bit

[Linus Walleij]

The PCLK for I2C4 is controlled by bit 10 in the PCKEN registers
while the KCLK is controlled by bit 9 on the KCKEN, it's
one of these odd assymetric things. Correct the PCLK bit to 10.

ChangeLog v1->v2:
- Actually do what the commit says and update the PCLK to bit
  10 instead of screwing with the KCLK. The KCLK was right all the time.
