PWM0 is the PWM associated with the LCD backlight.  Enable it.

The PMIC interrupt pinctrl line was added to the rk3288-evb-act8846,
but it's the same line on both the ACT8846 version and the RK808
version.  This makes a lot of sense since they share the same SoC
daugherboard.  Move the pinctrl definition to the common file so we
can use it for the RK808 version.

NOTE: The PMIC interrupt doesn't _actually_ go to the PMIC on the
ACT8846 version of the board (it does on the RK808), but our
convention is to label things as they're labelled on the schematics.
In the very least you can argue that this is the interrupt from the
PMIC daughtercard even if it doesn't actually go to the PMIC chip.

This enables basic SD and eMMC support.  Things are not yet running at
the fastest speed and we don't have the regulators specified, but we
can at least use the eMMC and SD cards now.

A note:
* Though MMC DDR50 mode is partially supported in the dw_mmc
  rk3288-specific code in Addy's patch, Addy's patch doesn't add
  tuning support.  That means DDR50 mode is not reliable.  From the
  3288 TRM: "Tuning is required for other speed modes-such as
  DDR50-even though the output delay from the card is less than one
  cycle."  Thus, we don't enable MMC DDR50 mode in this patch.

This is the top USB port on the evb (the one closest to the Ethernet
connector).

There is no phy driver that works on the Rockchip board for either USB
host port yet.  For now just hardcode the vbus signal to be on all the
time which makes both the dwc2 host and the EHCI port work.

There exist 2 variants using either the act8846 or rk808 as pmic, while the
rest of the board stays the same.
