imx:mx6 fix return value of mxc_get_clock
mxc_get_clock's return type is unsigned int. 'return -1' is same with
'return 0xffffffff', so 0 should be used as the return value when
unsupported mxc_clock type is passed to mxc_get_clock.
Also include an err message when unsupported mxc_clock type is passed
to mxc_get_clock.
