Subject: [PATCH 5.8 076/118] i2c: mediatek: Fix generic definitions for bus frequency

From: Qii Wang <qii.wang@...iatek.com>

[ Upstream commit ff6f3aff46beb3c29e0802cffcc559e1756c4814 ]

The max frequency of mediatek i2c controller driver is
I2C_MAX_HIGH_SPEED_MODE_FREQ, not I2C_MAX_FAST_MODE_PLUS_FREQ.
Fix it.

Fixes: 90224e6468e1 ("i2c: drivers: Use generic definitions for bus frequencies")
