ipmi: Increase polling rate to decrease boot time
The recent introduction of the IPMI-based HIOMAP transport for the PNOR
means the boot process is now heavily constrained by the speed of IPMI
transfers.
As an interim change to introducing interrupt-driven BT support,
decrease the period of the IPMI poller to increase boot speed by a
factor of about 1.7x when using the IPMI HIOMAP transport. This also
slightly increases the speed of a MBOX HIOMAP boot, but the point here
is that there's not a detrimental effect in this configuration.
