Subject: [PATCH v3 01/20] arm64: dts: mediatek: mt8183: Change iospaces for thermal and svs

The SVS iospace starts at 0x1100bc00 and not at 0x1100b000 as the
latter is the thermal sensor iospace instead.

Change the iospaces for both as following:
 - Thermal: 0x1100b000, length 0xc00
 - SVS: 0x1100bc00, length 0x400

Please note that while this would be a breaking change for SVS (but
not for thermal sensors), it doesn't matter because the svs driver
never worked anyway because of the missing trips in tzts2, causing
that thermal zone to never actually register, hence the SVS driver
to fail probing anyway.
