[d-kernel] [PATCH] config: Disable DEBUG_INFO_BTF on aarch64

[Vitaly Chikunov]

We have the same kernel for enterprise systems (like TaiShan) and toy
computers (like Raspberry Pi). Raspberry Pi cannot boot newer kernels
with U-Boot anymore[1] due to vmlinuz (that is uncompressed Image[2])
size approaching 40MB, (which is limited by fdt_addr_r=0x02600000
parameter specified in our U-Boot package).

Obvious target to reduce size is removing .BTF section. As a downside
this will reduce eBPF & tracing abilities on these platforms.
