bus: brcmstb_gisb: Use register offsets with writes too



This commit corrects the bug introduced in commit f8083587
("bus: brcmstb_gisb: Look up register offsets in a table") such
that gisb_write() translates the register enumeration into an
offset from the base address for writes as well as reads.
