From: Wenhui Sheng <wenhui.sh...@amd.com>
The legacy way to initialize discovery_tmr_size
is using DISCOVERY_TMR_SIZE, while after we reduce
DISCOVERY_TMR_SIZE from 64KB to 4KB, variable
discovery_tmr_size is also reduced to 4KB, this is not
correct, it still should be 64KB, discovery_tmr_size
will be used to calculate ip_discovery reserved mem's
start address and size.
Using DISCOVERY_TMR_OFFSET to init discovery_tmr_size instead.
