ARM: lpc32xx: stop overwriting TEST_CLK_SEL
While the UDA1380 is described in some lpc3250 device trees, there is currently no real user of that codec. Anyway, if the codec needs a clock, it should take it explicitly. lpc3250_machine_init is called for all the lpc32xx machines and some are using test1_clk (for example to strobe an HW watchdog). Overwriting TEST_CLK_SEL prevents booting those platforms.
