MLK-18744 usb: typec: tcpm: qos handling fix

Commit 661b7ec2359e ("MLK-17921-2 staging: typec: tcpm: add qos for
PD transfer") introduce qos for tcpm transfer between typec controller
and CPU, but the request and remove are not balanced well, the initial
request should be moved to tcpm_port_register as tcpm_init will be called
for every hard reset, and also move qos hold&release to where port state
changes.

MLK-18531 usb: typec: don't do vbus source disable for dead battery

In PTN5110 design, DisableSourceVBUS command also disables the sink
enable signal because the EN_SNK can be used to source higher voltage,
and, there is only one TCPC command to disable sourcing voltage without
telling whether to disable 5V or the high voltage, and to keep the
design simple they designed the PTN5110 to disable both. with this
fact, we use the flag drive_vbus to check if the source vbus enable was
issued, if yes we then do vbus source disable, in dead battery case,
we never did vbus source enable, so will not issue vbus source disable

MLK-19455 tick/nohz: Prevent bogus softirq pending warning

Commit 0a0e0829f990 ("nohz: Fix missing tick reprogram when interrupting an
inline softirq") got backported to stable trees and now causes the NOHZ
softirq pending warning to trigger. It's not an upstream issue as the NOHZ
update logic has been changed there.

The problem is when a softirq disabled section gets interrupted and on
return from interrupt the tick/nohz state is evaluated, which then can
observe pending soft interrupts. These soft interrupts are legitimately
pending because they cannot be processed as long as soft interrupts are
disabled and the interrupted code will correctly process them when soft
interrupts are reenabled.

Add a check for softirqs disabled to the pending check to prevent the
warning.

will try to power off a domain used by devices in genpd_sync_poweroff

Due to power domain is alway off, so no need to check device wakeup

MLK-19517-07 brcmfmac: remove "arp_hostip_clear" from "brcmf_netdev_stop"

The firmware does not respond ARP request and causes ping failed with
following steps.

1. Bring up interface
   ifconfig wlan0 up or start wpa_supplicant
2. Set the IP address
   ifconfig wlan0 192.168.100.10
3. Bring down interface or
   ifconfig wlan0 down or kill wpa_supplicant
4. Bring up interface again and set the same IP address
5. Connect to AP(192.168.100.1) and ping to AP will be failed.

FMAC clears arp_hostip when bringing down the interface, but not set it
back if setting the same IP address. We are able to see the IP address
in interface info(inconfig wlan0) but the ping still cannot work because
the firmware ARP offload does not respond the ARP request.
Because of that, we remove "arp_hostip_clear" from function
"brcmf_netdev_stop"
