The doc [1] doesn't define the endianness, but the kernel driver
uses readl() to access the registers, so we can guess it depends
on the architecture endianness.

As riscv architecture endianness is little it might not change anything
for it.

Moreover, android implementation uses DEVICE_NATIVE_ENDIAN [2]
