Hou Zhiqiang e44abfed6f PCI: dwc: Add accessors for write permission of DBI read-only registers 
The read-only DBI registers can be written only when the "Write to RO
Registers Using DBI" (DBI_RO_WR_EN) field of MISC_CONTROL_1_OFF is set.

Add accessors to enable and disable write permission, and use them instead
of accessing MISC_CONTROL_1_OFF directly.
