mmc: sdhci-esdhc-imx: Propagate ESDHC_FLAG_HS400* only on 8bit bus

Browse Source 
The core issues the warning "drop HS400 support since no 8-bit bus" when
one of the ESDHC_FLAG_HS400* flags is set on a non 8bit capable host. To
avoid this warning set these flags only on hosts that actually can do
8bit, i.e. have bus-width = <8> set in the device tree.
