UPSTREAM: drm/rockchip: Always signal event in next vblank after cfg_done

This patch makes the driver send the pending vblank event in next vblank
following the commit, relying on vblank signalling improvements done in
previous patches. This gives us vblank events that always represent the
real moment of changes hitting on the screen (which was the case only
for complete FB changes before) and lets us remove the manual window
update check.

UPSTREAM: debugfs: add debugfs_lookup()

We don't always have easy access to the dentry of a file or directory we
created in debugfs. Add a helper which allows us to get a dentry we
previously created.

The motivation for this change is a problem with blktrace and the blk-mq
debugfs entries introduced in 07e4fead45e6 ("blk-mq: create debugfs
directory tree"). Namely, in some cases, the directory that blktrace
needs to create may already exist, but in other cases, it may not. We
_could_ rely on a bunch of implied knowledge to decide whether to create
the directory or not, but it's much cleaner on our end to just look it
up.

ARM: dts: rockchip: rk3368-sheep add vsel gpio for syr827

Add vsel gpio for syr827, which is PMIC_SLEEP in hardware pcb.

The driver will parse the gpio and use it to indicate the chip
work status, as the following codes:

static int fan53555_is_enabled ()
if defined vsel_gpio
gpiod_get_raw_value
else
regmap_read

Before the patch, the log shows:
CPU4: update cpu_capacity 1024

  cache: parent cpu4 should not be sleeping
rk3x-i2c ff650000.i2c: timeout, ipd: 0x10, state: 1

Since cpu4 is the base core for cluster1, which need to initialize
cpufreq during boot up, finally call fan53555_is_enabled. But the
i2c is suspended at that time, can't get interrupt until timeout.

phy: rockchip-inno-usb2: delay suspending phy if plug out device

The otg_sm_work will suspend the usb2 phy immediately
if it detects disconnection from host. However, the usb2
controller(e.g. DWC2) may need to reinit registers and
reset usb core after usb disconnect, and it needs to
keep the usb2 phy stay in power on state to get utmi clk
for these usb controller operation. We don't have a good
synchronization mechanism to operate usb2 phy between
usb2 phy driver and usb2 controller driver, so we delay
4s to suspend phy if detect otg device disconnect from
host, this can make sure that usb2 controller completes
reinitialization before suspend usb2 phy.
