orangepioneplus: use U-Boot v2026.01 and TF-A lts-v2.12.9

[AbdulKus]

Fixes #9521.

This pins orangepioneplus to the same bootloader generation that restored proper PSCI secondary CPU bring-up on tested hardware:

• TF-A / BL31: lts-v2.12.9
• U-Boot: v2026.01

Tested on a real Orange Pi One+ board.

Before this change:

smp: Bringing up secondary CPUs ...
CPU1: failed to come online
CPU2: failed to come online
CPU3: failed to come online
SMP: Total of 1 processors activated.

After this change:

psci: PSCIv1.1 detected in firmware.
smp: Bringing up secondary CPUs ...
SMP: Total of 4 processors activated.
CPU: All CPU(s) started at EL2

This PR intentionally keeps the change minimal and scoped only to orangepioneplus.

📝 Walkthrough

Walkthrough

Added a new configuration function for Orange Pi One+ that pins specific bootloader versions: U-Boot v2026.01 and TF-A lts-v2.12.9. This addresses CPU core bring-up failures where only CPU0 was previously coming online.

Changes

Cohort / File(s)	Summary
Orange Pi One+ Bootloader Configuration config/boards/orangepioneplus.csc	Added post_family_config__use_orangepioneplus_uboot() function that sets ATFBRANCH, BOOTPATCHDIR, BOOTBRANCH_BOARD, and BOOTBRANCH variables to specific versions required for multi-core CPU support.

Poem

🐰 A rabbit hops with CPU cores full,
Four CPUs dance in harmony so cool,
No more the lone core standing still,
Orange Pi One+ climbs every hill! ✨

This may affect all H6 boards, so change should be done at family level.
Anyway if this change is confirmed working I'll probably include here #9381
