[PATCH net-next 05/30] net: dsa: mt7530: read XTAL value from correct register

From: Arınç ÜNAL <arinc.unal@arinc9.com>

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

Although the document MT7621 Giga Switch Programming Guide v0.3 states that
the value can be read from both registers, use the register where the
macros were defined under.
