Carsten Hansen fe81d9c959 feat(zynqmp): add pin group for lower qspi interface
ZynqMP provides two QSPI interfaces on MIO[0..12],
but the existing pin group definitions only allow
all or none of the pins to be configured for QSPI.

This is an issue on platforms that use only the lower
QSPI interface and require the remaining pins to be
configured for other purposes such as general I/O.

Add pin groups to support QSPI on MIO[0..4] with SS
(slave select) on MIO5, freeing up MIO[7..12] for
other uses.

The new pin groups can be accessed from Linux as
'qspi0_1_grp' and 'qspi_ss_1_grp'.
