Change the .section directive for the AVR assembler so that the .noinit section is always given the ELF NOBITS section type. 

PR gas/23570
	* config/tc-avr.c (md_pseudo_table): Add entry for "secction".
	(avr_set_section): New function.  Ensures that the .noinit section
	gets the NOBITS ELF section type.
