clk: at91: Read "reg" with helper

The "reg" property is an address-sized DT cell property. The AT91
compat clock parser only uses a small bus id from it, but reading it
with the u8 helper does not match the property encoding.

Use of_property_read_reg() so the code goes through the helper for
"reg" properties, then keep the existing range check before passing
the bus id to the clock registration code.
