[U-Boot] [PATCH 1/5] ARM: dts: socfpga: Flag reset manager on A10 as pre-reloc
The Altera reset manager block must be available very early on, since it controls ie. UART resets. Flag it as pre-reloc.

The UART0 and UART1 resets are missing from DT, so the reset manager cannot control them. Add the missing DT reset entries.

Add the GMAC0,1 OCP resets, which must also be ungated for those GMACs to work and add GMAC2 reset and OCP resets which were missing altogether.

The A10 SoCDK is missing the I2C bus alias, so DM I2C cannot assign the I2C bus a bus number. Add the missing alias.
