soc: qcom: geni-se: Fix write to read-only firmware buffer

geni_find_protocol_fw() casts fw->data to a non-const struct se_fw_hdr
pointer and writes back the rounded-up fw_size value:

        sefw->fw_size_in_items = cpu_to_le16(fw_size);

The firmware subsystem maps the firmware blob read-only. Writing through
the cast pointer causes a level-3 permission fault on AArch64 and
crashes the kernel during driver probe.

The write-back is no longer necessary: geni_find_protocol_fw() now
propagates the rounded size to the caller via fw_size_out. Remove the
write-back and make sefw (and the hdr pointer in the caller)
const-correct.
