drivers/char/agp/hp-agp.c - mismatch between SPDX and MODULE_LICENSE

[Joe Perches <coupons@perches.com>]

(SPDX mismatches found using this grep)

$ git grep --name-only 'MODULE_LICENSE("GPL and add' -- '*.c' | xargs grep SPDX
drivers/char/agp/hp-agp.c:// SPDX-License-Identifier: GPL-2.0-only
drivers/dma-buf/selftest.c:/* SPDX-License-Identifier: MIT */
drivers/gpu/drm/ttm/ttm_module.c:/* SPDX-License-Identifier: GPL-2.0 OR MIT */
drivers/gpu/drm/vboxvideo/vbox_drv.c:// SPDX-License-Identifier: MIT
drivers/gpu/drm/vmwgfx/vmwgfx_drv.c:// SPDX-License-Identifier: GPL-2.0 OR MIT

Back in 2003, the (fullhist) commit below perhaps inappropriately
removed license text that allowed arbitrary changes to source
code while adding 'MODULE_LICENSE("GPL and additional rights");'

Today, the license for this file is:

// SPDX-License-Identifier: GPL-2.0-only

So there is a mismatch between the SPDX identifier and the
MODULE_LICENSE in the file.

So the SPDX identifier now seems inappropriate.
Perhaps that can be rectified somehow...
 
commit 229f2fcdfa1377fb20174e6990460d8c60d33ada

    rework as per Linus' suggestion. Chipset drivers are now seperate modules
    that use the pci driver interfaces, and register with the agpgart backend.
