Subject: [PATCH 1/2] mmc: sdhci-of-aspeed: Uphold clocks-on post-condition of set_clock()

Precedence: bulk

The early-exit didn't seem to matter on the AST2500, but on the AST2600
the SD clock genuinely may not be running on entry to
aspeed_sdhci_set_clock(). Remove the early exit to ensure we always run
sdhci_enable_clk().
