The optee driver uses specific page table types to verify if a memory
region is normal. These types are not defined in nommu systems. Trying
to compile the driver in these systems results in a build error:

  linux/drivers/tee/optee/call.c: In function ‘is_normal_memory’:
  linux/drivers/tee/optee/call.c:533:26: error: ‘L_PTE_MT_MASK’ undeclared

     return (pgprot_val(p) &amp; L_PTE_MT_MASK) == L_PTE_MT_WRITEALLOC;
                             ^~~~~~~~~~~~~
                             PREEMPT_MASK
  linux/drivers/tee/optee/call.c:533:26: note: each undeclared identifier is
     reported only once for each function it appears in

     return (pgprot_val(p) &amp; L_PTE_MT_MASK) == L_PTE_MT_WRITEALLOC;
                                            ^~~~~~~~~~~~~~~~~~~

Make the optee driver depend on MMU to fix the compilation issue.

<content type='text'>
Currently the memory allocation failure checks on drv_data and
amdtee are using IS_ERR rather than checking for a null pointer.
Fix these checks to use the conventional null pointer check.

<content type='text'>
Currently, if tee_device_alloc() fails, then tee_device_unregister()
is a no-op. Therefore, skip the function call to tee_device_unregister() by
introducing a new goto label 'err_free_pool'.
