MLK-10808-4 imx: Move system counter driver to imx-common

Since the system counter driver will also be used by mx6ul, move
this timer driver to imx-common and rename it as syscounter.c

For mx6ul and mx7, configurations are used for choose the GPT timer
or system counter timer (default).

GPT timer:              CONFIG_GPT_TIMER
System counter timer:   CONFIG_SYSCOUNTER_TIMER
