rtc: gemini/ftrtc010: rename driver and symbols
The Gemini RTC is actually a generic IP block from Faraday Technology names FTRTC010. Rename the driver file and all symbols to match this IP name. The relationship can be clearly seen in the U-Boot driver posted by Po-Yu Chuang for the Faraday A320 board: https://lists.denx.de/pipermail/u-boot/2009-September/061326.html Remove the dependency on ARCH_GEMINI but select the driver for ARCH_GEMINI so we get a smooth transition. The IP block is synthsized on different silicon and architectures.
