[ Upstream commit 1ed5c3b22fc78735c539e4767832aea58db6761c ]
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.
