part: add support for Anlogic ELF2 EF2M45 

Anlogic EF2M45 is a FPGA with a co-packaged 4Mbit SPI Flash, and the
JTAG interface is the same with EG4S20.

Add support for it by adding it to the part database.

SPI Flash programming and SRAM programming are both tested.

The support of EF2M45 is also documented in this commit.
