v3 changes:
- PATCH 1/2 v3
 - Based on review comments reverted to using the 'clock-frequency' field
   in sdhci-brcmstb controller node for the sdio_freq clock 
- PATCH 2/2 v3
  - use devm_clk_get_optional() to get sdio_freq clock
  - look for clock-frequency value if set in the sdhci-brcmstb dt node
  - Added pmops to unprepare, prepare sdio_freq clock on suspend/resume
    in addition to the sdhci_pltfm_suspend/resume()  

v2 changes :
- Added Reviewed-by tag to PATCH v2 1/2
- In PATCH v2 2/2 Used host->mmc->f_max instead of parsing the device
  tree again, /s/clock-frequency/max-frequency in commit message 

v1 Changes :
Sending the remaining 2 patches separately after implementing review comments
for the patches 3/4 and 4/4 as part of the following:
"mmc: sdhci-brcmstb: host controller clock enhancements"
