tee: remove flags TEE_IOCTL_SHM_MAPPED and TEE_IOCTL_SHM_DMA_BUF
These look to be leftover from an early edition of this driver. Userspace
does not need this information. Checking all users of this that I have
access to I have verified no one is using them.
They leak internal use flags out to userspace. Even more they are not
correct anymore after a45ea4efa358. Lets drop these flags before
someone does try to use them for something and they become ABI.
