The PCI Local Bus Specification Revision 3.0 requires that
multi-function devices always implement function 0. Because of
this, enabling UFS (PCI device 12.7) requires ISH (PCI device 12.0)
to be enabled as well.

In order to enable the UFS controller (PCI device 12.7), the PCI
specification says that the device at function 0 in the same slot must
also be enabled, which is the ISH. Therefore, this CL enables both
the UFS controller and ISH.

This CL adds the delay time 50 ms and 20 ms into the RTD3 sequence,
the reason is that the rise and fall times of each signal
may differ by board, and so those board-specific delays
must be taken into account when power sequencing.
We checked power on sequence requires enable pin prior to reset pin,
so added delay to meet the sequence.
