Subject: [PATCH] clk: samsung: correct clock summary for hsi1 block

When debugfs is mounted to check clk_summary, 'mout_hsi1_usbdrd_user'
shows 400Mhz instead of 40Mhz. Snippet of the clock summary is given
as below

dout_shared2_div4           1 1 0 400000000 0 0 50000 Y ...
  mout_hsi1_usbdrd_user     0 0 0 400000000 0 0 50000 Y ...
    dout_clkcmu_hsi1_usbdrd 0 0 0 40000000  0 0 50000 Y ...

Hence corrected the clk-tree for the cmu_hsi1 & the corrected clock
summary is as mentioned below.

dout_shared2_div4           1 1 0 400000000 0 0 50000 Y ...
  mout_clkcmu_hsi1_usbdrd   0 0 0 400000000 0 0 50000 Y ...
    dout_clkcmu_hsi1_usbdrd 0 0 0 40000000  0 0 50000 Y ...
      mout_hsi1_usbdrd_user 0 0 0 40000000  0 0 50000 Y ...
