Video PLL factors can be set in a way that final PLL rate is outside
stable range. H6 user manual specifically says that N factor should not
be below 12. While it doesn't says anything about maximum stable rate, it
is clear that PLL doesn't work at 6.096 GHz (254 * 24 MHz).
Set minimum allowed PLL video rate to 288 MHz (12 * 24 MHz) and maximum
to 2.4 GHz, which is maximum in BSP driver.

MUX bits for MMC clock register range are 25:24 where 24 is shift
and 2 is width So fix the width number from 3 to 2.

On the H6, the MMC module clocks are fixed in the new timing mode,
i.e. they do not have a bit to select the mode. These clocks have
a 2x divider somewhere between the clock and the MMC module.
To be consistent with other SoCs supporting the new timing mode,
we model the 2x divider as a fixed post-divider on the MMC module
clocks.
This patch adds the post-dividers to the MMC clocks, following the
approach on A64.

Currently the register offset of the PWM bus gate in Allwinner H6 clock
driver is wrong.
Fix this issue.

The bus clocks (AHB/APB) on Allwinner H6 have their second divider start
at bit 8, according to the user manual and the BSP code. However,
currently the divider offset is incorrectly set to 16, thus the divider
is not correctly read and the clock frequency is not correctly calculated.
Fix this bit offset on all affected bus clocks in ccu-sun50i-h6.

The Allwinner H6 CCU has a "HDMI Slow Clock", which is currently missing
in the ccu-sun50i-h6 driver.
Add this missing clock to the driver.

The Allwinner H6 SoC has a CCU which has been largely rearranged.
Add support for it in the sunxi-ng CCU framework.
