[PATCH 7/7] Platform/RaspberryPi: Correct device path removal.

["Jeremy Linton" <jeremy.linton@arm.com>]

The "arasan" driver now works with the emmc2 device.
This means that both the PcdSdIsArasan and the
!PcdSdIsArasan result in valid SD controllers on the rpi4.

Lets avoid removing the "stale" boot entry, in this case
which also has the side effect of avoiding a boot assert
when emmc2 is selected.
