From: Bartosz Golaszewski <bartosz.golaszewski@linaro.org>

qseecom_scm_dev(), qseecom_dma_alloc() and qseecom_dma_free() are no
longer used following the conversion to using tzmem. Remove them.

Fixes: 6612103ec35a ("firmware: qcom: qseecom: convert to using the TZ allocator")
Reviewed-by: Andrew Halaney <ahalaney@redhat.com>
