Fix compilation for target gdbserver on CRISv32 platform.

Fix compilation for target gdbserver on CRISv32 platform.

One misspelled function call, and one superfluous typedef. The latter
causes an error of the following type when building:

linux-crisv32-low.c:372: error: conflicting types for 'elf_gregset_t'
/.../target/include/asm/elf.h:36:
error: previous declaration of 'elf_gregset_t' was here

	* linux-crisv32-low.c (elf_gregset_t): Delete typedef.
	(initialize_low_arch): Call init_registers_crisv32 rather than
	init_register_crisv32.
