Change-Id: I42170d51a517170b58d532addd9c38496e43457c

jasmine_sprout: Remove QTI perfd

Bug: 69270928
Test: Build and boot device and test camera
Change-Id: I87b283206f462fb5c8ec9cdd303ae2934fe9bfc4

jasmine_sprout: Declare BOARD_VENDOR

* Needed for xiaomi-perfmgr power AIDL guards

Change-Id: Idbb48e0f9b01090a456ad5d3f2d51f4dfab55672

jasmine_sprout: Create dummy libqti-perfd-client

* proprietary perfd blobs can finally be nuked without breaking goodix
* we could even map the functions to use libperfmgr powerhints in the future

[SebaUbuntu]: Cleanup Android.bp and add copyright header

Change-Id: I124652f3041761966a3e3bd97c757fecc39cc5fb

jasmine_sprout: libqti-perfd-client: Remove namespace declaration

It's pointless when using extern "C".

Change-Id: Ibdf9f06a70aa3a75687b33781c78cf2172bb334d

jasmine_sprout: libqti-perfd-client: return a dummy value

Return a positive integer for perf lock acquire and release so
that Goodix/FPC fingerprint sensor blobs will not complain.

Goodix:
E [goodixHAL][gf_hal_milan_f_series]: goodix_perf_lock_acquire: Failed to acquire perf lock, err: 0
E [goodixHAL][gf_hal_milan_f_series]: goodix_perf_lock_release: Perf lock release error 0

FPC:
E fpc_tac : fpc_perf_lock_acquire: Incorrect params, Failed to acquire perf lock, err
E fpc_tac : fpc_perf_lock_release: Perf lock release error 0

jasmine_sprout: libqti-perfd-client: Move to C

* Why bothering with C++ mangling when we can just build it as a standard C library?

Change-Id: I45ea977edf7ea7fab6fece76f3049654a8d24c5d

jasmine_sprout: Add powerhint.json jasmine

Change-Id: If270fc906fd833bb6b0d3b00621c0b079346e47d

jasmine_sprout: rootdir: Initial libperfmgr init config

* From coral, heavily stripped down

Change-Id: Ib6846e4f4f23baf56910d2330e26846b99830218

jasmine_sprout: sepolicy: Initial libperfmgr sepolicy

Change-Id: I3d0a259bc89b4ecd0bf1632199172710d98230e0

jasmine_sprout: Don't explicitly build older minor version HIDL libs

Change-Id: Ib0caa49054a79b1f01ffc751826286a29c642e06

jasmine_sprout: Remove QTI perf reminants

jasmine_sprout: Add back ro.vendor.extension_library definition

 * We aren't using QCOM's perfd but our blobs still check for this.
 * To avoid unnecessary errors, let's just add it back.
