ARM clock is sourcing from pll1_sw, and pll1_sw can be either from
pll1_sys or step, so we should enable arm clock during clock
initialization instead of pll1_sys, otherwise, arm clock's usecount

ARM: keystone: enable DMA zone for LPAE

Keystone II peripheral devices support 32-bit DMA and hence can access only
first 2GB of the memory address space. So set the platform dma_zone_size
to handle that case.

for ARCH_KEYSTONE, but it does not enable BE by default.
