[PATCH 20/25] at91sam9m10g45ek, at91sam9m10ihd, pm9g45: move reset vector to board code

[Sam Ravnborg]

These three board share the same at91sam9g45_lowlevel_init.c file.

Introduce lowlevel.c file for the boards that contains the reset vector.
Delete the now unused at91sam9g45_lowlevel_init.c file
Drop unused CONFIG symbols and Makefile references
