[Buildroot] [PATCH 1/4] boot/arm-trusted-firmware: Disable bin copy for rk3399

[sunil at amarulasolutions.com <sunil@amarulasolutions.com>]

From: Jagan Teki <jagan@amarulasolutions.com>

Unlike other SoC platforms, rockchip platforms doesn't require a binary
generation on TF-A project.

This is due to rockchip platforms have non-continuous memory areas in
the linker script with a huge gap between them, so generating the binary
would require addition padding which indeed increases the size of the binary.

Interestingly this binary generation is disabled in v2.2 of TF-A on below
commit:
 commit <33218d2a8143> "rockchip: Disable binary generation for all SoCs."

So, select default binary boot images as *.bin only if it's not rk3399.

This fixes the atf build on rk3399 with v2.2.

Note: the same can be applied to rest of rockchip platforms if
they use v2.2 TF-A.
