mips: pci-mt7620: do not print NFTS register value as error log

These codes are used to read NFTS_TIMEOUT_DELAY register value and
write it into kernel log after writing the register. they are only
used for debugging during driver development, so there is no need
to keep them now.

Tested on MT7628AN router Motorola MWR03.
