arm/ixp4xx: Rename FREQ macro to avoid collisions

FREQ is a ridiculously short name for a platform-specific macro in a
generic header, and it now conflicts with an enumeration in the
gspca/ov519 driver.

Also delete conditional reference to ixp4xx_get_board_tick_rate()
which is not defined anywhere.
