[U-Boot] [PATCH v4 02/15] Makefile: Fix mrproper make target

[Anup Patel]

Currently, the mrproper make target tries to force remove all
"arch/*/include/asm/arch" paths assuming they are symlinks but
this prevents us from adding place-holder headers under the
arch/riscv/include/asm/arch directory.

To solve this, we fix mrproper make target to only remove
"arch/*/include/asm/arch" paths which are symlinks and do
nothing for paths which are directory.
