CRIS v32: Fix startup oops and replace hardcoded pagesize in vmlinux.lds.S
- Move alignment of init data to page size outside define CONFIG_BLK_DEV_INITRD
This avoids oops due to memory on the same page as init data being freed.
- Change hardcoded page size to use macro from asm/page.h
- Add reserved memory via CONFIG_ETRAX_VMEM_SIZE.
- Use available defines for TEXT_TEXT and INITCALLS.
- Cleanup whitespace.
