[PATCH] staging: rtl8188eu: make efuse_power_switch() function static

[Alexandru Ardelean]

The `rtl8188eu` driver is built as a kmod in order to avoid symbol
conflicts (at link-time) with other Realtek drivers.

Internally, we use this driver as builtin [vs kmod], and we've identified
the `efuse_power_switch()` symbol to be conflicting at link-time with the
one from the `rtlwifi` driver.

An alternative solution would have been to rename the function, but it
doesn't look like it's being used outside of this driver, so just make it
static.
