GSI Driver get the usage count in work handler when set_alt 1 happens
and this counter will decrement in disconnect work due to cable disconnect
or in gsi_suspend for suspended state.
In this case set alt to 0 came for MBIM interface and clear the
data_interface_up flag. After that suspend happens and does not decrement
the counter in gsi_suspend. This causes a mismatch of usage count and
usb not entering to low power mode.
Fix this by checking for USB_PROT_GPS_CTRL instead of data_interface_up.

Some hosts enable function remote-wakeup immediately after
enumeration. But they don't perform function_suspend before U3
and also don't disable function remote-wakeup even if entering
deep sleep state and don't intend to wakeup from USB. One of the
reason could be that they rely on device to initiate remote-wakeup
only if it function suspended. Hence, update the check to initiate
function remote-wakeup only if device is function suspended.

Currently, certain controllers with lower core clock rates, takes
more than 32ms to set the halted bit. This results in XHCI halt
timeout.
Fix this by increasing the timeout to 48ms.

pte_accessible() is used by ptep_clear_flush() to figure out whether TLB
invalidation is necessary when unmapping pages for reclaim. Although our
implementation is correct according to the architecture, returning true
only for valid, young ptes in the absence of racing page-table
modifications, this is in fact flawed due to lazy invalidation of old
ptes in ptep_clear_flush_young() where we elide the expensive DSB
instruction for completing the TLB invalidation.
Rather than penalise the aging path, adjust pte_accessible() to return
true for any valid pte, even if the access flag is cleared.

During composition switch, android driver stops data transfers first
and removes configuration before disabling the pullup. With this sequence
there is a possibility for a race where usb_remove_config is in progress
during which pullup is active and sending the setup request for strings
with zero configuration value. Hence fix the issue by adding spinlock
protection for get_sring descriptor.
