Subject: [PATCH v2 2/5] clk: pxa: core pll is not affected by t bit

The t bit of clkfcfg doesn't affect the core pll clock, but it makes core
clock select between core pll clock and core run clock.

As such remove it from the core pll rate reporting function, while it
remains in clk_pxa27x_core_get_parent().
