usb: gadget: s3c-hsotg: fix build on x86 and other architectures
The readsl and writesl I/O accessors are only defined on some
architectures. The driver currently depends on CONFIG_ARM because
the build breaks on x86, in particular. Switch to use of ioread32_rep
and iowrite32_rep to fix build on all architectures and remove the
CONFIG_ARM dependency.
Also update printk formatting to handle a long long dma_addr_t to avoid
warnings on !32-bit architectures.
