This is missing the s3c-sdhci.1 mmc_busclk.0 as 4th entry which is defined in 
s3c2443-clock.c. The pclk for hsmmc1 is common to S3C2416/2450 and S3C2443 and 
is therefore defined in plat-s3c24xx [S3C2443 only has a hsmmc1 to be exact].

Also it would be nice to include the hsmmc-clock in mach-s3c2443/clock.c too. 
The sdhci support there seems to be incomplete but it would be nice to have 
the clocks similar to everything else if anyone wants to start on this arch.
