With this commit, we can set hwlock user id in DT with
"rockchip,hwlock-user-id" property, if it is not set, the driver
use default value 0x01 instead.

drm_atomic_helper_connector_commit() is rockchip private function, so
rename to rockchip_drm_atomic_helper_connector_commit() is more reasonable.

when rtk(also some others) wifi/bt combo chips suspend, it
disconnect from bt-remote control unit(RCU). when RCU's
powerkey pressed, it will send ble broadcast to rtk bt chip.
As the rtk chips receive the broadcast, it should wake up
the host, but it can't send bt-hid powerkey to host because
it had lost communication with host.
So,it just send a IRQ pulse to host. The host should resume
from suspend.
Because the RCU just send a IRQ pulse, so rk chips just resume
by IRQ and then go to sleep again for no power-key event.
this is not expected. we expect to power up system wholly.
With this path, we try to power up the system. so we add a
power-up key event when BT IRQ received.
We also can control the "/proc/bluetooth/sleep/powerupkey"
node to enable or disable this function.

Fix it by masking all misc interrupts before registering rk_pcie_sys_irq_handler.
And later, they will be unmasked already.

In some case, the pll rate will be change to get a target
rate for it's child. we want set the pll rate closest to
the max pll rate. However, It's not all the rate can get
a set of legal paramters to config the pll. So when this
case happen, we try a lower rate as the target pll rate.
