[yocto] [meta-raspberrypi][PATCH] u-boot: Fix appending to RDEPENDS

[Jonathan Liu]

The += operator should not be used in combination with overrides as it
will clear any existing values in the variable.

Example:
FOO = "bar"
FOO_rpi += "baz"

The above example would result in FOO being equal to " baz" instead of
"bar baz".

The bbappend is changed to use a wildcard instead of a specific version
to simplify updating U-Boot.
