[PATCH 14/17] nova-core: remove an unnecessary register read: HWCFG1

[Joel Fernandes <joelagnelf@nvidia.com>]

From: John Hubbard <jhubbard@nvidia.com>

This register read is not required in order to bring up any of the GPUs,
and it is read too early on Hopper/Blackwell+ GPUs anyway. So just stop
doing this.
