This patch does following improvements to the SBRST extension
documentation:
1) The reset_type and reset_reason are 32bit parameters so
fix sbi_system_reset() function prototype accordingly
2) Use caption for various tables and use cross-reference
to cite the tables from text
3) Mention SBI verion in SRST function listing
