[RFC:avr] use regcache instead of read_register

["Theodore A. Roth" <troth@openavr.org>]

Hi,

The ARI caught this and it seems like a trivial change. There is a bit of 
confusion though in the use of current_regcache since the ARI says this:

  current regcache 57 Replace current_regcache with explict parameter

What would that explicit parameter be?

If this patch is ok, it brings the ARI count for the AVR down to 0.

	* avr-tdep.c (avr_read_pc): Use regcache instead of read_register.
	(avr_read_sp): Ditto.
