CorebootModulePkg: Change CbParseAcpiTable prototype to avoid gcc fail

Use of void** as a generic pointer to pointer is a Microsoft extension
to the C language and is not supported by gcc. Without this change, gcc
compile fails with error:
passing argument 1 of 'CbParseAcpiTable' from incompatible pointer type
note: expected 'void **' but argument is of type
'struct EFI_ACPI_3_0_ROOT_SYSTEM_DESCRIPTION_POINTER **'
