timer: goldfish: Use __raw_readl()

Browse Source 
The Goldfish timer registers are native endian, so they act as
big-endian on the m68k virt machine. Currently, this driver uses
readl(), which works by luck because it's currently broken on m68k.

Use __raw_readl() instead to avoid breaking this driver when the
endianness of readl() is fixed.
