net: designware_eqos: fix left shift count >= width of type CI builds with -Werror, including -Werror=shift-count-overflow, which fails for STM32MP enabled platform that use EQOS on a 32-bit platform.
As des1 will have always been programmed to zero on a 32-bit platform, we can just suppress the warning with a cast.
