mmc: sdhci-of-at91: make function sdhci_at91_set_uhs_signaling static

Colin Ian King · storulf · commit 519c51af0d17 · 2017-10-30T11:46:01.000+01:00
The function sdhci_at91_set_uhs_signaling  is local to the source and does
not need to be in global scope, so make it static.

Cleans up sparse warning:
symbol 'sdhci_at91_set_uhs_signaling' was not declared. Should it be
static?
