[PATCH] fixup! net: designware_eqs: set upper 32bit address for DMA descriptors to support 64-bit addressing

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

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.
