linux-postmarketos-qcom-msm8974: upgrade to 5.14.14

Last update for 5.14 kernel, next one will be 5.15

Kernel config cleanup:

• enable various USB peripherals support, per user requests:
  • usb webcams (uvcvideo) [m]
  • usb ethernet adapters [m]
• remove support for various TV tuners and DVB cards - faster builds and less size maybe :)
• enable few filesystem drivers [m], like iso9660, exFAT, ntfs
• enable kernel automounter, to use with nfs mounts (autofs, [m])
• disable CONFIG_ARM_CPUIDLE, which gets rid of annoying message during boot: /cpus/cpu@0: unsupported enable-method property: qcom,kpss-acc-v2. Cpuidle is handled by another driver, which is still enabled: CONFIG_ARM_QCOM_SPM_CPUIDLE

I've tested upgrade procedure and rebooting afterwards - works fine on klte & hammerhead, no regressions expected for minor version upgrade.

$ sudo apk upgrade -i

P.S. 5.15-rc branch is ready, it works too, but why hurry? when 5.15(.1) is released - switching to it will be fast ;)
