[U-Boot] [PATCH 0/5] Add wait_for_bit()

[Mateusz Kulikowski]

This series add generic function to poll register waiting for
one or more bits to change.

Very similar function was used in several drivers:
- dwc2
- ohci-lp32xx
- ehci-mx6
- zynq_gem

First patch adds function, following patches update drivers and
board config files / defconfigs.

This series was compile-tested with buildman for ~50 boards
(most or even all boards affected by change)

Code was also run-tested on ehci-msm driver (not yet in mainline)

There is single difference in behavior: ohci-lp32xx driver will
not print "Timeout..." message with debug disabled.
I think it's not a big issue as this driver seems unused, but
if it's an issue - please drop that patch.
