[edk2-platforms][PATCH 1/1] Platform/RPi4/ConfigDxe: Replace SD Host with eMMC2 SDHCI option

["Pete Batard" <pete@akeo.ie>]

From: Andrei Warkentin <andrey.warkentin@gmail.com>

SD Host is not usable on Pi 4 so replace it with an eMMC2 option.

Note that is a menu only change at this stage, since we don't have
eMMC support finalized.
