Subject: [PATCH net-next 06/24] net: dsa: mt7530: read XTAL value from correct register

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

On commit 7ef6f6f8d237 ("net: dsa: mt7530: Add MT7621 TRGMII mode support")
bit mask macros were added under the MT7530_HWTRAP register to read the
crystal frequency. However, the value given to the xtal variable on
mt7530_pad_clk_setup() is read from the MT7530_MHWTRAP register instead.

It doesn't seem to matter as my testing on MCM and standalone MT7530 shows
the value is correctly read from both registers but change it anyway.
