The R-Car Gen4 PCIe controller integration configures MSI registers
in the controller driver .init callback, because those registers
have to be configured while PERST signal is asserted, and the PERST
signal is asserted across the controller driver .init callback.
The registers have to be configured differently in case the iMSI is
or is not used. Assign pp->use_imsi_rx before the controller driver
.init callback is called, so the controller driver .init callback
implementation can use the pp->use_imsi_rx value.
