ipmi_si: Phytium S2500 workaround for MMIO-based IPMI

phytium inclusion
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I4RK58


CVE: NA

--------------------------------

The system would hang up when the Phytium S2500 communicates with
some BMCs after several rounds of transactions, unless we reset
the controller timeout counter manually by calling firmware through
SMC.
