soc: qcom: pil-msa: Disable ahb clock during modem ramdump collection 



On targets with the ahb_clk_vote DT flag, the ahb clock needs to be
disabled in the ramdump collection path. Hence, replace the
pil_mss_shutdown call during modem ramdump collection with the
pil_mss_deinit_image which does the cleanup done in pil_mss_shutdown
and additionally also disables the ahb clock.
