Merge tag 'qcom-drivers-for-6.7-2' of https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into soc/drivers

More Qualcomm driver updates for v6.7

The Qualcomm SMC an QSEECOM drivers are moved into a "qcom"
subdirectory, to declutter the base directory. Missing include guards
are added to the qseecom header file. Unneded extern specifiers are
removed from the scm call wrappers.

__counted_by is added to the apr_rx_buf structure, in the APR driver.

Lastly in the pmic_glink driver the pmic_glink drm_bridge type is
corrected to DisplayPort, over the incorrect "USB" value. The return
values are added to error prints for the various typec set() calls.

* tag 'qcom-drivers-for-6.7-2' of https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux:
  soc: qcom: pmic_glink_altmode: Print return value on error
  firmware: qcom: scm: remove unneeded 'extern' specifiers
  firmware: qcom: scm: add a missing forward declaration for struct device
  firmware: qcom: move Qualcomm code into its own directory
  soc: qcom: apr: Add __counted_by for struct apr_rx_buf and use struct_size()
  soc: qcom: pmic_glink: fix connector type to be DisplayPort
  firmware: qcom: qseecom: add missing include guards
