[PATCH V1 0/2] Fix hibern8 enter failure during host reset

[Nitin Rawat <quic_nitirawa@xxxxxxxxxxx>]

Commit <52a518019c> ("Fix missing clk change notification on host reset")
added clock scaling notification to ufshcd_host_reset_and_restore.
This invokes hibern8 enter and exit on qualcomm platform which fails
because controller is in reset state.

Fix this by checking the Host controller state before sending
hibern8 command.

__ufshcd_wl_resume()
ufshcd_reset_and_restore()
ufshcd_host_reset_and_restore()
ufshcd_scale_clks()
ufshcd_vops_clk_scale_notify()
ufs_qcom_clk_scale_notify()
ufshcd_uic_hibern8_enter()

Fixes: 52a518019ca1 ("scsi: ufs: core: Fix missing clk change notification on host reset")
