phy-rockchip-inno-hdmi: Fix RK3328_TERM_RESISTOR_CALIB_SPEED_7_0's third value
After commit "linux/bits.h: Add compile time sanity check of GENMASK
inputs" [1], arm64 defconfig builds started failing:

| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
As pointed out by Robin and Guenter, inno_write's val argument is an
8-bit value so having a mask larger than that doesn't make sense. This
also matches the rest of the *_7_0 macros in this driver.
