 * Name: access
 *
 * Description:
 *   The access() function shall check the file named by the pathname pointed
 *   to by the path argument for accessibility according to the bit pattern
 *   contained in amode, using the real user ID in place of the effective user
 *   ID and the real group ID in place of the effective group ID.
 *   As there are no users in NuttX, the function always succeeds.
 *
 * Parameters:
 *   path - a pointer to the path
 *   amode - the access mode
 *
 * Returned Value:
 *   Always OK (zero)
 *
 * Assumptions:
