[PATCH v2] can: mcp251x: not correct register address

[Tomas Krcka <tomas.krcka@nkgroup.cz>]

v2: fix of corrupted patch

This patch corrects addresses of acceptance filters.
These registers are not in use, but values should be correct.
Tested with MCP2515 and am3352 and also checked datasheets for MCP2515
and MCP2510.
