Update jtagspi driver for 1-, 2- and 4-byte addresses
jtagspi driver always used 3-byte addresses regardless of actual device capcity. Now select 1- to 4-byte addresses depending on device capacity. Some devices need a special command to activate the 4-byte address mode, a special command to accomplish this, and a further command for setting device properties are added. Additionally, restriction (start of range had to be page aligned) removed. Tested with XCS6SLX16 board and W25Q256FV in 3- and 4-byte address modes.
