[PATCH RFC 6/8] clk: sunxi-ng: a733: Add mod clocks support

[Enzo Adriano]

Hi Junhui,

Register check for the mod clocks in this patch against the public A733
User Manual V0.92: 88 of the 94 mod/mux clock entries match the manual's
register offsets, with the documented gating/mux/divider layout at each
offset. The six that have no register in the public manual are the set
already discussed in this thread for provenance notes - avs (0x0880),
spi4 (0x0F28), sgpio (0x1060), lpc (0x1080), gmac1-phy (0x1420) - plus
one more: tcon-lcd2 (0x1510); the manual only documents VO0_TCONLCD0
(0x1500) and VO0_TCONLCD1 (0x1508).

Thanks,
Enzo
