ACPI, APEI, EINJ, Fix resource conflict on some machine
Some APEI firmware implementation will access injected address
specified in param1 to trigger the error when injecting memory error.
This will cause resource conflict with RAM.
On one of our testing machine, if injecting at memory address
0x10000000, the following error will be reported in dmesg:
APEI: Can not request iomem region <0000000010000000-0000000010000008> for GARs.
This patch removes the injecting memory address range from trigger
table resources to avoid conflict.
