85xx/b4:Correct USB DR controller liodn entry

LIODN entry for B4860/B4420 mentions USB controller as "mph"
insread of "dr". This results in PAMU not permitting bus
transactions for USB DR controller on B4860 resulting in
USB function failure. Replacing "fsl-usb2-mph" with
"fsl-usb2-dr" allows USB DR controller bus transactions
