2014-01-09cpu/allwinner/a10: Add low-level helpers for DRAM clock controlAlexandru Gagniuc
PLL5 is special in that it controls the DRAM clock, and requires a fine-grained low-level control which will be needed by raminit code. This change also brings functionality which will be needed by raminit.

This bit is not documented in the datasheet, but is used in the upcoming RAM init code.

2014-01-08cpu/allwinner/a10: Refactor API for gating clocks to peripheralsAlexandru Gagniuc
Rather than having to track which bit in which register should be cleared or set to gate or ungate the clock to a certain peripheral, provide a simplified enum which encodes the register and bit. This change comes with a function which decodes the enum and gates/ungates the clock. This also removes the register-dependent bitmasks for APB0 and APB1 gating registers.
