soc/amd/stoneyridge/chip.c: Move setup_bsp_ramtop to soc_init()

Issue first reported at commit 1587dc8a2b, the call of functions
setup_bsp_ramtop() and setup_uma_memory() should be moved from enable_dev()
to soc_init(). The function setup_uma_memory() no longer exists, its
functionality transfered to agesawrapper_amdinitpost.

Move setup_bsp_ramtop() as required.

BUG=b:62240756
TEST=Build and boot kahlee.
