nxphlite-v3:SDHC setting is for EMI issue with GPS and FCC (#11029)

This updating of the driver setting is for EMI issue with GPS and FCC.
   With this setting the clock is sinusoidal

   N.B. sd_bench fails on SanDISK HC, but Passes SanDISK **HC1** and
   Kingston cards.

   ****Use HC1 or Kingston cards!***

   Testing done on SanDISK HC all failed sd_bench with Drive/Slew other
   than default and _PIN_OUTPUT_FAST|_PIN_OUTPUT_HIGHDRIVE

	_PIN_OUTPUT_FAST|_PIN_OUTPUT_HIGHDRIVE    Square noisy, pass SanDISK HC
        _PIN_OUTPUT_FAST|_PIN_OUTPUT_LOWDRIVE     Square noisy, pass SanDISK HC
        _PIN_OUTPUT_HIGHDRIVE|_PIN_OUTPUT_SLOW    sinusoidal fail SanDISK HC, pass SanDISK HC1
        _PIN_OUTPUT_LOWDRIVE |_PIN_OUTPUT_SLOW    sinusoidal fail SanDISK HC, pass SanDISK HC1
                              _PIN_OUTPUT_SLOW    sinusoidal fail SanDISK HC, pass SanDISK HC1
