[PATCH] NIOS2: setup.c: drop unused variable 'dram_start'

From: Randy Dunlap
Date: Fri Sep 24 2021 - 17:05:29 EST

This is a nuisance when CONFIG_WERROR is set, so drop the variable
declaration since the code that used it was removed.

../arch/nios2/kernel/setup.c: In function 'setup_arch':
../arch/nios2/kernel/setup.c:152:13: warning: unused variable 'dram_start' [-Wunused-variable]
152 | int dram_start;

Fixes: 7f7bc20bc41a ("nios2: Don't use _end for calculating min_low_pfn")
