* config/tc-avr.c (mcu_types): Rename avr4 to avr5, add avr4.
Add more MCU types for avr4 and avr5. Replace at94k{10,20,40}
with just at94k. Change AVR_ISA_85xx back to AVR_ISA_2xxx.
(md_show_usage): Update usage message.
(md_parse_option): Allow redefinition of MCU type within the
same avr[1-5] bfd machine type. Show both old and new MCU type
in the error message.
(md_apply_fix3): Support 8K wrap if AVR_ISA_MEGA is not set.
Simplify 8K wrap code.
