LF-1088 PCI: imx: pcie rc can't access ep's memory
RC can't access EP's DDR memory on i.MX8MQ/i.MX8MM platforms.
Rootcause: The BAR# of EP are not configured correct.
The BAR# offset is 1Mbytes on i.MX8MQ/i.MX8MM, but is 4Kbytes on
other i.MX platforms(e.x 6/7/8QM/8QXP/8MP).
Correct the BAR# access offset on i.MX8MQ/i.MX8MM to fix it.
Let DBI always be writeable in EP/RC validation system.
