usb-storage: Add ignore-residue quirk for NXP PN7462AU



commit 2aa48857ad52236a9564c71183d6cc8893becd41 upstream.

This is USB mass storage primary boot loader for code download on
NXP PN7462AU.

Without the quirk it is impossible to write whole memory at once as
device restarts during the write due to bogus residue values reported.
