Allwinner clock changes for 4.16

Browse source

Fixed-post-divider support is added for two types of our clocks.
 This in turn is used to support odd clocks on some of our SoCs.
 On the A64, the MMC module clocks have a hidden post-divider.
 On the A83T, a post-divider is needed to support programming
 sigma-delta modulation with known fixed parameters from the
 BSP kernel for the audio PLL.
 
 There's also a small cleanup to use the shorter PTR_ERR_OR_ZERO
 macro in various functions.
