[0/2] Change the sg2042 timer layout to fit aclint format

As the sg2042 uses different address for timer and mswi of its clint
device, it should follow the aclint format. For the previous patchs,
it only use only one address for both mtime and mtimer, this is can
not be parsed by OpenSBI. To resolve this, separate these two registers
in the dtb.
