Subject: [PATCH] MIPS: ralink: export rt_sysc_membase for rt2880_wdt.c

[ Upstream commit fef532ea0cd871afab7d9a7b6e9da99ac2c24371 ]

rt2880_wdt.c uses (well, attempts to use) rt_sysc_membase. However,
when this watchdog driver is built as a loadable module, there is a
build error since the rt_sysc_membase symbol is not exported.
Export it to quell the build error.

ERROR: modpost: "rt_sysc_membase" [drivers/watchdog/rt2880_wdt.ko] undefined!

Fixes: 473cf939ff34 ("watchdog: add ralink watchdog driver")
