xtensa: boot: don't add include-dirs

[ Upstream commit 54d3d7d363823782c3444ddc41bb8cf1edc80514 ]

Drop the -I<include-dir> options to prevent build warnings since there
is not boot/include directory:

cc1: warning: arch/xtensa/boot/include: No such file or directory [-Wmissing-include-dirs]

Fixes: 437374e9a950 ("restore arch/{ppc/xtensa}/boot cflags")
Fixes: 4bedea945451 ("xtensa: Architecture support for Tensilica Xtensa Part 2")
