efi_selftest: Remove loadfile2 for initrd selftests

Browse source 
We are redefining how u-boot locates the initrd to load via the kernel
LoadFile2 protocol.  This selftest is not relevant any more, so remove
it. A new one will be added later

* Copyright (c) 2020 Ilias Apalodimas <ilias.apalodimas@linaro.org>
*
* This test checks the FileLoad2 protocol.
* A known file is read from the file system and verified.
*
* An example usage - given a file image with a file system in partition 1
* holding file initrd - is:
*
* * Configure the sandbox with
*
* CONFIG_EFI_SELFTEST=y
* CONFIG_EFI_LOAD_FILE2_INITRD=y
* CONFIG_EFI_INITRD_FILESPEC="host 0:1 initrd"
*
* * Run ./u-boot and execute
*
* host bind 0 image
* setenv efi_selftest load initrd
* bootefi selftest
*
* This would provide a test output like:
*
* Testing EFI API implementation
*
* Selected test: 'load initrd'
*
* Setting up 'load initrd'
* Setting up 'load initrd' succeeded
*
* Executing 'load initrd'
* Loaded 12378613 bytes
* CRC32 2997478465
*
* Now the size and CRC32 can be compared to the provided file.
