reset: socfpga: add an early reset driver for SoCFPGA
Create a separate reset driver that uses the reset operations in reset-simple. The reset driver for the SoCFPGA platform needs to register early in order to be able bring online timers that needed early in the kernel bootup. We do not need this early reset driver for Stratix10, because on arm64, Linux does not need the timers are that in reset. Linux is able to run just fine with the internal armv8 timer. Thus, we use a new binding "altr,stratix10-rst-mgr" for the Stratix10 platform. The Stratix10 platform will continue to use the reset-simple platform driver, while the 32-bit platforms(Cyclone5/Arria5/Arria10) will use the early reset driver.
