The controller doesn't seem to pick-up on clock changes, so set the
SDHCI_QUIRK_CAP_CLOCK_BASE_BROKEN flag to query the clock frequency

Force emmc2's frequency to 150MHz as the default 100MHz (set by FW)
seems to interfere with the VPU clock when setup at frequencies bigger
than 500MHz (a pretty common case). This ends up causing unwarranted
SDHCI CMD hangs when no SD card is present.
Signed-off
Users might want to choose a different clock frequency than whatever the
bootloader provided at probe time. Add 'clock-frequency' bindings.

configured at 500MHz or more, lower clocks are OK.
There is no specific command that will time out, it seems random.
I found out that by bumping the controller's frequency to 150MHz the
issue disapears. So let's do that.
