[PATCH 1/2] firmware: stratix10-rsu: fix 32-bit compilation

[Rosen Penev <rosenp@gmail.com>]

The code uses long which is changes depending on CONFIG settings.
However, these longs should really be 64-bit. Fixes at least the
following errors:

drivers/firmware/stratix10-rsu.c: In function ‘rsu_get_spt_callback’:
