ACPI, APEI bug fix

For supporting APEI to work well, I make 4 patches for fixing some bugs.
- the first and the second patch fixed the wrong checking for ERST and EINJ tables' header.
- the third one fixed the wrong return value of acpi_pre_map.
- the last one fixed the unsuitable usage of platform_data.
