ENGR00331706-1 imx: gpt: Add 24Mhz OSC clock source support for GPT

Introduce a new configuration "CONFIG_MXC_GPT_HCLK". When it is set,
the GPT will use 24Mhz OSC as clock source. Otherwise, the GPT will
use 32Khz OSC as clock source.

Since only the GPT on iMX6 series provide the clock source option for
24Mhz OSC. For other series(MX5), if the configuration is set, the
perclk will be selected as clock source.

MX6Q/D Rev 1.0 and MX6SL can't use the 24Mhz OSC clock source option,
so select the perclk for them. For MX6SL, we will set the OSC 24Mhz to
perclk in CCM, so eventually the clock comes from OSC 24Mhz.
