board: dragonboard410c: Fix RAM size

Browse Source 
DB410c has exactly 1 GiB of RAM. Some of it is reserved, but this is
described separately in the DT.

This was fixed before in commit 1d667227ea51 ("board: dragonboard410c: Fix
PHYS_SDRAM_1_SIZE"), but was reintroduced when DB410c was converted to use
the upstream device tree.

Note that there are variants of apq8016-sbc with 2 GiB RAM (e.g. the
Geniatech DB4). They need the WIP SMEM memory map parsing [1] to use the
full amount of RAM.
