The code selecting a device for the sdhci host has been
continuously tweaked (4b711cb13843f5082e82970dd1e8031383134a65
"mmc: sdhci-pltfm: Add structure for host-specific data" and
a4d2177f00a5252d825236c5124bc1e9918bdb41 "mmc: sdhci-pltfm: dt
device does not pass parent to sdhci_alloc_host" while there
does not seem to be any reason to use platform device's parent
in the first place.
The comment saying "Some PCI-based MFD need the parent here"
seem to refer to Timberdale FPGA driver (the only MFD driver
registering SDHCI cell, drivers/mfd/timberdale.c) but again,
the only situation when parent device matter is runtime PM,
which is not implemented for Timberdale.
