Subject: [PATCH] mmc: sdhci-pxav3: Fix Sparse warning of duplicate set_uhs_signaling entry

This fixes below sparse warning:
drivers/mmc/host/sdhci-pxav3.c:227:10: warning: Initializer entry defined twice
drivers/mmc/host/sdhci-pxav3.c:232:10:   also defined here

by removing duplicate initialization of .set_uhs_signaling in
struct sdhci_ops. Also does away with duplcated function.
