mmc: sdhci-pxav3: fix setting of pdata->clk_delay_cycles
commit 14460dbaf7a5a0488963fdb8232ad5c8a8cca7b7 upstream.
Current code checks "clk_delay_cycles > 0" to know whether the optional
"mrvl,clk_delay_cycles" is set or not. But of_property_read_u32() doesn't
touch clk_delay_cycles if the property is not set. And type of
clk_delay_cycles is u32, so we may always set pdata->clk_delay_cycles as a
random value.
This patch fix this problem by check the return value of of_property_read_u32()
to know whether the optional clk-delay-cycles is set or not.
