xhci: fix event ring segment table related masks and variables in header
xHC controller can supports up to 1024 interrupters.
To fit these change the max_interrupters varable from u8 to u16.
Add a separate mask for the reserve and preserve bits [5:0] in the erst
base register and use it instead of the ERST_PRT_MASK.
ERSR_PTR_MASK [3:0] is intended for masking bits in the
event ring dequeue pointer register.
