If we enable SPL and SKIP_LOWLEVEL_INIT, this results in the weak
function timer_init() being used in the SPL build. This is not
desirable as on iMX6 SoC, MMC will then fail once u-boot proper is
booted due to timing issue.

Fixes: be277c3a89 ("imx: mx7: avoid some initialization if low level is skipped")
