Subject: [PATCH net-next 11/13] net: dsa: mt7530: refactor
 MT7530_PMEEECR_P()

From: Arınç ÜNAL <arinc.unal@...nc9.com>

The MT7530_PMEEECR_P() register is on MT7530, MT7531, and the switch on the
MT7988 SoC. Rename the definition for them to MT753X_PMEEECR_P(). Use the
FIELD_PREP and FIELD_GET macros. Rename GET_LPI_THRESH() and
SET_LPI_THRESH() to LPI_THRESH_GET() and LPI_THRESH_SET().
