arm: socfpga: Sync Cyclone V DK PLL configuration

Sync SoCFPGA Cyclone V development kit pinmux configuration with
Rocketboard U-Boot v2013.01.01-114-g9381569 (ACDS14.1_REL_GSRD_PR).

NOTE: This change is useless until we get proper SPL support, at
      which point this will likely need further rework.
