During the submission of the clk-rk3568 driver, some bugs
were fixed, so the mainline driver is slightly different
than ours.

Backport those changes.

Before the change: The sizeof rk3568_pll_rates = 2544
Use union: The sizeof rk3568_pll_rates = 1696

In future Soc, more PLL types will be added, and the
rockchip_pll_rate_table will add more members,
and the space savings will be even more pronounced
by using union.

The cpll clk gate bits had an ordering issue. This led to the loss of
the boot sdmmc controller when the gmac was shut down with:
`ip link set eth0 down`
as the cpll_100m was shut off instead of the cpll_62p5.
cpll_62p5, cpll_50m, cpll_25m were all off by one with cpll_100m
misplaced.

This reverts commit e544eba0.

Rockchip's v4.19 kernel is removing this operating
point on some of the boards. Looking at the datasheet,
it's also unclear if the SoC can tolerate this voltage.

Let's remove it.

The TCS4525 has 128 voltage steps. With the calculation set to 127 the
most significant bit is disregarded which leads to a miscalculation of
the voltage by about 200mv.

Fix the calculation to end deadlock on the rk3566-quartz64 which uses
this as the cpu regulator.

We allocate 2MB chunks at a time, so it might appear that a page fault
has already been handled by a previous page fault when we reach
panfrost_mmu_map_fault_addr(). Bail out in that case to avoid mapping the
