[PATCH AUTOSEL 4.20 012/105] mfd: at91-usart: Add platform dependency

From: Sasha Levin

[ Upstream commit 628f3dfe4c7b35bbe63ec194ca6da857b00b0083 ]

It doesn't make sense to present option MFD_AT91_USART by default if
not building an AT91 kernel, as the drivers which depend on it are
not available.
