omap: iovmm: don't check 'da' to set IOVMF_DA_FIXED flag
Currently IOVMM driver sets IOVMF_DA_FIXED/IOVMF_DA_ANON flags according to input 'da' address when mapping memory: da == 0: IOVMF_DA_ANON da != 0: IOVMF_DA_FIXED It prevents IOMMU to map first page with fixed 'da'. To avoid such issue, IOVMM will not automatically set IOVMF_DA_FIXED. It should now come from the user throught 'flags' parameter when mapping memory. As IOVMF_DA_ANON and IOVMF_DA_FIXED are mutually exclusive, IOVMF_DA_ANON can be removed. The driver will now check internally if IOVMF_DA_FIXED is set or not.
