staging: mt7621-dts: fix cpuintc and fixedregulator dtc warnings, fix xhci

Fix the cpuintc and fixedregulator dtc warnings:

Warning (unit_address_vs_reg): /cpuintc@0: node has a unit name, but no reg property
Warning (unit_address_vs_reg): /fixedregulator@0: node has a unit name, but no reg property
Warning (unit_address_vs_reg): /fixedregulator@1: node has a unit name, but no reg property
Warning (unique_unit_address): /cpuintc@0: duplicate unit-address (also used in node /fixedregulator@0)

Remove the unnecessary status = "okay" property from the xhci node.
