spi: aspeed: Fix missing __iomem annotation in output transfer path

The dst parameter of aspeed_spi_user_transfer_tx() is an MMIO address
obtained from chip->ahb_base, but it was typed as void * instead of
void __iomem *.  This caused a sparse warning report. Fix the
parameter type to void __iomem * and drop the now-unnecessary
cast at the call site.
