943f7fddaa usb: xhci: move doorbell array pointer assignment 
Move the assignment of the doorbell array pointer from xhci_mem_init()
to xhci_init(). The assignment now utilizes the newly introduced
xhci_set_doorbell_ptr() function.

Doorbell Array Offset mask (DBOFF_MASK) is updated to directly specify its
bit range as 31:2, rather than using inverted reserved bits 1:0.
This change simplifies the mask representation, making it more intuitive
and easier to understand.

Remove the "// " prefix from trace messages, as it is unnecessary and
distracting.

c35ba0ac48 XHCI: Separate PORT and CAPs macros into dedicated file 
Split the PORT and CAPs macro definitions into a separate file to
facilitate sharing with other files without the need to include the entire
xhci.h.
