Subject: [PATCH 1/4] clk: sunxi-ng: v3s: Fix TCON reset de-assert bit
According to the datasheet and the reference code from Allwinner, the
bit used to de-assert the TCON reset is bit 4, not bit 3.
Fix it in the V3s CCU driver.

Subject: [PATCH 2/4] clk: sunxi: A31: Fix wrong AHB gate number
According to the manual the gate clock for MMC3 is at bit 11, and NAND1
is controlled by bit 12.
Fix the gate bit definitions in the clock driver.

Subject: [PATCH 3/4] clk: at91: fix at91sam9x5 peripheral clock number
nck() looks at the last id in an array and unfortunately,
at91sam9x35_periphck has a sentinel, hence the id is 0 and the calculated
number of peripheral clocks is 1 instead of a maximum of 31.
