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
