[RFC PATCH v5 24/24] DO NOT MERGE: only to make CI happy

[Francis Laniel]

This commit set CONFIG_HUSH_PARSER_2021 as the default to trigger the CI with
this parser.

Nonetheless, Some boards are not compatible with new 2021 hush parser:
1. rcar3_ulcb:
	When built with CONFIG_HUSH_PARSER_2021, the u-boot.img file size
	exceeds the 1MB file limit of 890 bytes:
	aarch64:  +   rcar3_ulcb
	+u-boot.img exceeds file size limit:
	+  limit:  0x100000 bytes
	+  actual: 0x10037a bytes
	+  excess: 0x37a bytes
	Some complementary work is then needed to use CONFIG_HUSH_PARSER_2021 for this
	board.
	As CONFIG_BOOTCOMMAND is quite simple for this board, I think we can gain some
	bytes by deactivating hush features like if and loop.
2. the keymile (i.e. VENDOR_KM) family:
	This boards used set_local_var() to store some variables as local shell.
	They then used get_local_var() to retrieve the variables values.
	Sadly, this two functions do not exist with CONFIG_HUSH_PARSER_2021.
	A patch was proposed to use environment variables rather than local variables
	but it does not tackle the problem, so complementary work is needed to make
	this boards use CONFIG_HUSH_PARSER_2021 [1].
