serial: 8250_pericom: Revert "Re-enable higher baud rates"

Browse Source 
UPF_MAGIC_MULTIPLIER is userspace available bit and can be changed
at any time. There is no sense to rely on it to be always present.

This reverts commit b4ccaf5aa2.

Note, that code was not reliably worked before, hence it implies
no functional change.
