[PULL 53/54] hw/timer/renesas_tmr: Prefix constants for CSS values with CSS_

[Peter Maydell]

The #defines INTERNAL and CASCADING represent different possible
values for the TCCR.CSS register field; prefix them with CSS_ to make
this more obvious, before we add more defines to represent the
other possible values of the field in the next commit.
