net: davinci_emac: Fix incorrect masking of tx and rx error channel
[ Upstream commit d83b8aa5207d81f9f6daec9888390f079cc5db3f ]
The bit-masks used for the TXERRCH and RXERRCH (tx and rx error channels)
are incorrect and always lead to a zero result. The mask values are
currently the incorrect post-right shifted values, fix this by setting
them to the currect values.
(I double checked these against the TMS320TCI6482 data sheet, section
5.30, page 127 to ensure I had the correct mask values for the TXERRCH
and RXERRCH fields in the MACSTATUS register).
Addresses-Coverity: ("Operands don't affect result")
Fixes: a6286ee630f6 ("net: Add TI DaVinci EMAC driver")
