[PULL 01/13] ppc/pnv: Move SBE host doorbell function to top of file

[Harsh Prateek Bora <harshpb@linux.ibm.com>]

From: Aditya Gupta <adityag@linux.ibm.com>

Moved 'pnv_sbe_set_host_doorbell' as-it-is to above
'pnv_sbe_power9_xscom_ctrl_write'.

This is done since in a future patch, S0 interrupt implementation uses
'pnv_sbe_set_host_doorbell', hence the host doorbell function needs to
be declared/defined before 'pnv_sbe_power9_xscom_ctrl_write' where we
implement the S0 interrupt.

No functional change.
