staging: dgnc: tty.c: updates uart_struct declaration for sparse
This patch edits the type casts neo_uart_struct and
cls_uart_struct. A previous patch added the marker __iomem
to these structs. This patch ensures that the change to
the marker is consistent. This also removes these
sparse warnings:
warning: incorrect type in assignment (different address spaces)
expected struct neo_uart_struct [noderef] <asn:2>*ch_neo_uart
got struct neo_uart_struct *<noident>
warning: incorrect type in assignment (different address spaces)
expected struct cls_uart_struct [noderef] <asn:2>*ch_cls_uart
got struct cls_uart_struct *<noident>
