boards: add saampixv1_1 bootloader target and board type mapping

[ashwanisihag]

Summary

Add bootloader support for saampixv1_1.

What this PR adds

• New bootloader target for saampixv1_1_bl
• Board type mapping for TARGET_HW_SAAMPIX_V1_1
• Hardware configuration for the SaamPix v1.1 board
• USB identification strings for bootloader detection

Notes

• This PR is paired with PX4-Autopilot PR feat(boards/saam_saampixv1_1): add board support for saampixv1_1 PX4-Autopilot#26902 for firmware target support.
• The board type and bootloader target are intended to enable standard PX4 firmware packaging and flashing flow for this board.

Validation

• Local bootloader build completed for saampixv1_1_bl
• CI results will confirm integration in upstream build environment

@davids5 CI is green now. This PR adds SaamPix v1.1 bootloader target and board type mapping and is ready for review when you have time.

@davids5 follow-up applied for the active hw_config.h thread.

Updated SAAMPIX bootloader USB PID in hw_config.h:

• USBPRODUCTID: 0x0030 -> 0x008E

This now matches the current PX4-Autopilot saampixv1_1 defconfig value so both repos are aligned while waiting for final Dronecode VID/PID confirmation.

[ashwanisihag]

Correction update: the prior PID change accidentally touched the MindPX block. Fixed now in commit d5297e7.

Current hw_config.h values:

• TARGET_HW_MINDPX_V2 USBPRODUCTID = 0x0030 (restored)
• TARGET_HW_SAAMPIX_V1_1 USBPRODUCTID = 0x008E (aligned with PX4-Autopilot)

[ashwanisihag]

@davids5 quick follow-up: all requested fixes are in, both review threads are resolved, and CI checks are green.

Could you please take another look when you have a moment?

[davids5]

@ashwanisihag Nice!

[ashwanisihag]

Addressed a runtime issue discovered during hardware verification: for TARGET_HW_SAAMPIX_V1_1, BOARD_TYPE now resolves to numeric board id 200 in bootloader responses (instead of macro-symbol expansion behavior).
Change pushed in commit: 7eee3be
This is a one-line SaamPix-only fix in hw_config.h and does not modify other board targets.
Could you please take another look? Thanks.
