configs: Add configurable GPU L1,L2 num banks and L2 latencies (#389)

Previously, the L1, L2 number of banks and L2 latencies were not
configurable through command line arguments. This commit adds support to
configure them through the arguments '--tcp-num-banks' for number of
banks in L1, '--tcc-num-banks' for number of banks in L2, and
'--tcc-tag-access-latency', and '--tcc-data-access-latency'
