[U-Boot] [PATCH v2 0/3] drivers: Add reset ctrl to drivers

[Ley Foon Tan]

Add reset ctrl to dwmmc socfpga, designware Ethernet and ns16550 serial drivers.

A reset property is an optional feature, so only print out a warning and
do not fail if a reset property is not present.
    
If a reset property is discovered, then use it to deassert, thus bringing the
IP out of reset.

This is preparation to upstream Intel Stratix 10 SoC support in [1].

v2 change:
- remove 'return' in designware emac driver
- keep reset control in socfpga_dw_mmc.c because it didn't call to common dwmmc probe
  function when in SPL.
- add reviewed-by in ns16550 patch
