Introduce a new configuration "CONFIG_MXC_GPT_HCLK". When it is set,
the GPT will select a high frequency clock as clock source.
Otherwise, the GPT will stay to use 32Khz OSC as clock source.
In the implementation, since only the GPT on i.MX6 series provide the
clock source option for 24Mhz OSC. For others (only i.MX5 and i.MX6
compile the driver), if the configuration is set, the perclk will be
selected as clock source.
MX6Q/D Rev 1.0 and MX6SL are special in the implementation, because they
don't have the 24Mhz OSC clock source option, so also 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.

The i.MX6 common timer uses the 32-bit variable tbl (time base lower)
to record the overflow of the 32-bit counter. I.e. if the counter
overflows, the variable tbl does overflow, too.
To capture this overflow, use the variable tbu (time base upper), too.
Return the combined value of tbl and tbu.
lastinc is unused then, remove it.

Define default SoC input clock frequencies for i.MX5/6 in order to get rid of
duplicated definitions.

Up now only MX5 and MX6 can share code, because they have
a common source directory in cpu/armv7. Other not armv7
i.MX can profit of the same shared code. Move these files
into a directory accessible for all, similar to plat-mxc
in linux.
