[PATCH] ARM: rockchip: atf: move PBL malloc space away from OP-TEE memory

[Sascha Hauer <s.hauer@pengutronix.de>]

We recently introduced initializing the PBL early memory pool which
might be needed for decompressing the BL31/BL32 firmware files. We
used the end of the first DRAM region for the pool and with this we
ended up exactly in the default OP-TEE memory region which is mapped
as faulting. Move the pool directly beneath the OP-TEE memory.

Fixes: 76b1f31275 ("ARM: rockchip: initialize PBL malloc")
