Re: [PATCH] PCI: rockchip-ep: Remove wrong mask on subsys_vendor_id

Remove wrong mask on subsys_vendor_id. Both the Vendor ID and Subsystem Vendor ID are u16 variables and are written to a u32 register of the controller. The Subsystem Vendor ID was always 0 because the u16 value was masked incorrectly with GENMASK(31,16) resulting in all lower 16 bits being set to 0 prior to the shift.

Remove both masks as they are unnecessary and set the register correctly i.e., the lower 16-bits are the Vendor ID and the upper 16-bits are the Subsystem Vendor ID.

This is documented in the RK3399 TRM section 17.6.7.1.17

Applied to controller/rockchip, thank you!
