cpufreq: mediatek: Raise proc and sram max voltage for MT7622/7623

cpufreq: mediatek: Raise proc and sram max voltage for MT7622/7623

[ Upstream commit 0883426fd07e39355362e3f2eb9aee1a154dcaf6 ]

During the addition of SRAM voltage tracking for CCI scaling, this
driver got some voltage limits set for the vtrack algorithm: these
were moved to platform data first, then enforced in a later commit
56a3b933a169 ("cpufreq: mediatek: Refine mtk_cpufreq_voltage_tracking()")
using these as max values for the regulator_set_voltage() calls.

In this case, the vsram/vproc constraints for MT7622 and MT7623
were supposed to be the same as MT2701 (and a number of other SoCs),
but that turned out to be a mistake because the aforementioned two
SoCs' maximum voltage for both VPROC and VPROC_SRAM is 1.36V.

Fix that by adding new platform data for MT7622/7623 declaring the
right {proc,sram}_max_volt parameter.
