reset: Add Allwinner RESET driver

Add common reset driver for all Allwinner SoC's.

Since CLK and RESET share common DT compatible, it is CLK driver
job is to bind the reset driver. So add CLK bind call on respective
SoC driver by passing ccu map descriptor so-that reset deassert,
deassert operations held based on ccu reset table defined from
CLK driver.

Select DM_RESET via CLK_SUNXI, this make hidden section of RESET
since CLK and RESET share common DT compatible and code.
