This enables the Broadcom uart bluetooth driver on uart0 and gives it
ownership of its gpios. In order to use this, you must enable the
following kconfig options:
- CONFIG_BT_HCIUART_BCM
- CONFIG_SERIAL_DEV
This is applicable to rk3288-veyron series boards that use the bcm43540
wifi+bt chips.
As part of this change, also refactor the pinctrl across the various
boards. All the boards using broadcom bluetooth shouldn't touch the
bt_dev_wake pin.

Use interpolated brightness tables (added by commit 573fe6d1c2
("backlight: pwm_bl: Linear interpolation between
brightness-levels") for veyron, instead of specifying every single
step. Some devices/panels have intervals that are smaller than
the specified 'num-interpolated-steps', the driver interprets
these intervals as a single step.
Another option would be to switch to a perceptual brightness curve
(CIE 1931), with the caveat that it would change the behavior of
the backlight. Also the concept of a minimum brightness level is
currently not supported for CIE 1931 curves.

veyron jaq, jerry, minnie and speedy have mostly redundant regulator
and pinctrl configurations for the panel/backlight. Consolidate these
pieces in the eDP .dtsi.
Also change the default power supply for the panel to
'panel_regulator', instead of overriding it in all the board files.
pinky is the only device that uses 'vcc33_lcd' (the prior default),
so overwrite it in this case. pinky doesn't have a complete display
configuration, to keep things as they were delete the common nodes
that didn't exist previously in pinky's board file.

This is like commit 0ca87bd5ba ("ARM: dts: rockchip: Add pin names
for rk3288-veyron-jerry") and commit ca3516b32c ("ARM: dts:
rockchip: Add pin names for rk3288-veyron-minnie") but for 3 more
veyron boards.
A few notes:
- While there is most certainly duplication between all the veyron
boards, it still feels like it is sane to just have each board have
a full list of its pin names. The format of "gpio-line-names" does
not lend itself to one-off overriding and besides it seems sane to
more fully match schematic names. Also note that the extra
duplication here is only in source code and is unlikely to ever
change (since these boards are shipped). Duplication in the .dtb
files is unavoidable.
- veyron-jaq and veyron-mighty are very closely related and so I have
shared a single list for them both with comments on how they are
different. This is just a typo fix on one of the boards, a possible
missing signal on one of the boards (or perhaps I was never given
the most recent schematics?) and dealing with the fact that one of
the two boards has full sized SD.

The panel which jaq uses requires the pwm duty cycle larger than 3%,
when the backlight status from power off to power on, otherwise the
backlight will flush, so we modify the second brightness-level to 8,
and when the backlight from power off to power on the pwm duty cycle
will larger than 3%.

The panels need a bit of time to actually turn on. If this isn't
observed, this results in problems when trying talk to the panels
and thus produces detection errors. 100ms seem to be a safe value
for the time being.
