soc: fsl: cpm1: qmc: Fix __iomem addresses declaration

Running sparse (make C=1) on qmc.c raises a lot of warning such as:
  ...
  warning: incorrect type in assignment (different address spaces)
     expected struct cpm_buf_desc [usertype] *[noderef] __iomem bd
     got struct cpm_buf_desc [noderef] [usertype] __iomem *txbd_free
  ...

Indeed, some variable were declared 'type *__iomem var' instead of
'type __iomem *var'.

Use the correct declaration to remove these warnings.
