ARM: dts: msm: Increase the dwc3 reg address range for Kona

The register address range for Kona is not covering all the
controller registers. Tuning the Tx deemph registers for dwc3
gen2 protocol test is not possible with the current range.
Modify the reg property to cover the entire range as defined
in the data book to fix this issue.
