[PATCH] drivers: firmware: ti_sci: Add DM_FLAG_PRE_RELOC to driver

[Manorit Chawdhry]

Currently the driver relies on bootph flag to probe it during PRE_RELOC
stage but with the upcoming cleanup of v6.13, we don't have the bootph
property in the parent nodes anymore and ti_sci driver being one of the
parent nodes required during SPL stage would end up hampering the probe
model [0].

Add DM_FLAG_PRE_RELOC to ti_sci driver for mitigating this issue.
