ipmi: Fix the I2C address extraction from SPMI tables
Unlike everywhere else in the IPMI specification, the I2C address specified in the SPMI table is not shifted to the left one bit with the LSB zero. Instead it is not shifted with the MSB zero. Reported-by: Sanjeev <singhsan@codeaurora.org> Signed-off-by: Corey Minyard <cminyard@mvista.com>
