The booting flow is SPL -> OpenSBI -> U-Boot.
The boot hart may change after OpenSBI and may not always be hart0,
so wrap the related branch instruction with M-MODE.
Current DTB setup for XIP is not valid.
There is no chance for CONFIG_SYS_FDT_BASE, the DTB address used
in XIP mode, to be returned. Fix this.

Commit 44645f87de ("mmc: Fix mmc_switch excessive timeout") introduced
a side effect where CMD13 SEND_STATUS is issued in case mmc_wait_dat0()
does not return -ENOSYS and $send_status is not set. This happens on all
hardware which does implement .mmc_wait_dat0 callback, e.g. i.MX8M .
This leads to lengthy timeout before booting OS in case of eMMC in one
of the HS200/HS400 modes, since the card cannot respond to CMD13 while
downgrading from HS200/HS400 to regular HS mode.
Fix this by adding the missing conditional.
