drivers: soc: qcom: Reorder pil loader in makefile

Subsys-pil-tz.c and pil-q6v5-mss.c has dependency on
peripheral-loader.c.  Pil_info_base needs to be first
set in msm_pil_init, so pil_desc_init can use that and
write subsystem image start address to memory.  Put
peripheral-loader.o before subsys-pil-tz.o and
pil-q6v5-mss.o, so the init call in peripheral-loader.c
will be called earlier.
