Subject: [PATCH] MdePkg: IndustryStandard: Rename ACPI SPCR revision 4
 structure

The structure for the SPCR revision 4 table was originally named
EFI_ACPI_4_0_SERIAL_PORT_CONSOLE_REDIRECTION_TABLE. This prefix suggests it
is an ACPI 4.0 structure, which it is not. This could cause confusion with
genuine ACPI 4.0 structures and defines (eg
EFI_ACPI_4_0_SERIAL_PORT_CONSOLE_REDIRECTION_TABLE_SIGNATURE, which is
unrelated to SPCR revision 4).

Rename the structure to EFI_ACPI_SERIAL_PORT_CONSOLE_REDIRECTION_TABLE_4.
