base-files: armsr: number Ten64 GPIOs according to kernel version

A change in kernel 6.2[1] caused the base numbers of GPIOs to
change significantly on some architectures like aarch64.

We have to number our GPIOs accordingly.
Ideally the board.d scripts should look through sysfs
to find the basenum (like cat "/sys/devices/platform/soc/2000000.i2c/
i2c-0/0-0076/gpio/gpiochip640/base"), but the problem is
that this occurs before modules are loaded, meaning I2C and other
runtime devices may be missing.
