arm: exynos: Fix PMU register configuration for local power blocks

For the six local power blocks - MFC, DISP1, GSC, MAU, G3D and ISP
the respective CMU_RESET, CMU_SYSCLK and CMU_CLKSTOP registers need
to be low initially for normal mode. This change has been updated
only in the latest Exynos5250 1.10 user manual. Also fix the AFTR
and LPA configurations even though they are not being used.

There are no known issues fixed by doing this, though had we done this
originally for CMU_RESET_ISP_SYS_PWR_REG I believe we wouldn't have
ever hit the problems that ISP ARM was causing us with suspend/resume
(we wouldn't have had the perfect poweroff sequence for ISP ARM but
wouldn't have hit issues).
