kmp204x: complete the reset sequence and PRST configuration

This adds the reset support for the following devices that was until
then not implemented:
- BFTIC4
- QSFPs

This also fixes the configuration of the prst behaviour for the other
resets: Only the u-boot and kernel relevant subsystems are taken out of
reset (pcie, ZL30158, and front eth phy).

Most of the prst config move to misc_init_f(), except for the PCIe
related ones that are in pci_init_board and the bftic and ZL30158 ones
that should be done as soon as possible.

Only the behavior of the Hooper reset is changed according to the
documentation as the application is not able to not configure the switch
when it is not reset.
