[PATCH 4/8] riscv: dts: thead: Add TH1520 GPIO ranges

[Drew Fustini]

From: Emil Renner Berthing <emil.renner.berthing at canonical.com>

Add gpio-ranges properties to the TH1520 device tree, so user space can
change basic pinconf settings for GPIOs and are not allowed to use pads
already used by other functions.

Adjust number of GPIOs available for the different controllers.
