[PATCH 3/6] ARM: Rockchip: fix clang warning about passing 32-bit register operand

[Ahmad Fatoum]

clangd warns that "Value size does not match register size specified by
the constraint and modifier".

Promote the subtraction result to unsigned long to fix this.

The 16 is likely unnecessary, but I am hesitant to remove it without testing.
