Subject: [PATCH] Ask user input only when CONFIG_X86 or CONFIG_COMPILE_TEST is
 set to y

From: Narendra K <Narendra.K@...l.com>

For the EFI_RCI2_TABLE kconfig option, 'make oldconfig' asks the user
for input as it is a new kconfig option in kernel version 5.4. This patch
modifies the kconfig option to ask the user for input only when CONFIG_X86
or CONFIG_COMPILE_TEST is set to y.

The patch also makes EFI_RCI2_TABLE kconfig option depend on CONFIG_EFI.

The patch is created on kernel version 5.4-rc1.

Hi Ard, I have made following changes -

- changed the prompt string from "EFI Runtime Configuration
Interface Table Version 2 Support" to "EFI RCI Table Version 2 Support"
as the string crossed 80 char limit. 

- added "depends on EFI" so that code builds only when CONFIG_EFI is
set to y.

- added 'default n' for ease of understanding though default is set to n.
