Remove Intel WiFi firmware from imx8mm-jaguar-sentai build

[ajlennon]

Issue

The imx8mm-jaguar-sentai machine configuration includes Intel WiFi firmware (iwlwifi-ty-a0-gf-a0-59.ucode) in firmware-imx_%.bbappend, but this appears to be unnecessary.

Current Situation

• sentai WiFi chipset: NXP IW612 (nxpiw612-sdio feature flag)
• Intel WiFi firmware: For Intel AX210 chips (ax210 feature flag)
• sentai feature flags: Does NOT include ax210, only has nxpiw612-sdio

Problem

The Intel WiFi firmware is being included in the sentai build even though:

1. sentai uses NXP IW612, not Intel AX210
2. sentai doesn't have the ax210 machine feature flag
3. Other machines that DO use Intel WiFi (inst, phasora) have the ax210 feature flag

Proposed Solution

Remove the Intel WiFi firmware entries for imx8mm-jaguar-sentai from:

• meta-dynamicdevices-bsp/recipes-kernel/firmware-imx/firmware-imx_%.bbappend
  • Remove SRC_URI:append:imx8mm-jaguar-sentai line
  • Remove do_install:append:imx8mm-jaguar-sentai() function

Verification Needed

Before removing, verify:

• sentai hardware actually uses NXP IW612 (not Intel AX210)
• No runtime dependencies on Intel WiFi firmware
• Test build and runtime after removal

This was identified while adding support for imx8mm-jaguar-dt510 which also uses NXP IW612 and correctly does NOT include Intel WiFi firmware.
