usb: host: fotg210-hcd: Remove unused variable 'hcc_params'
The result is actually read into fotg210->caps->hcc_params. No
need to popuate an unused varible with the unchecked return value
from fotg210_readl().
Fixes the following W=1 kernel build warning(s):
drivers/usb/host/fotg210-hcd.c: In function ‘fotg210_run’:
drivers/usb/host/fotg210-hcd.c:5013:6: warning: variable ‘hcc_params’ set but not used [-Wunused-but-set-variable]
5013 | u32 hcc_params;
