[PATCH 6.6 1/2] Revert "PCI: imx6: Skip controller_id generation logic for i.MX7D"

[Ryan Matthews <ryanmatthews@fastmail.com>]

This reverts commit 2a12efc567a270a155e3b886258297abd79cdea0 which is
commit f068ffdd034c93f0c768acdc87d4d2d7023c1379 upstream.

This is a backport mistake.

Deleting "IMX7D" here skips more than just controller_id logic. It skips
reset assignments too, which causes:

 imx6q-pcie 33800000.pcie: PCIe PLL lock timeout

In my case, in addition to broken PCIe, kernel boot hangs entirely.

This isn't a problem upstream because before this, they moved the rest of
the code out of the switch case.
