[PATCH 0/1][SRU][focal:linux-azure] Enable Android ASHMEM and BINDER_IPC modules

[Tim Gardner-2]

BugLink: https://bugs.launchpad.net/bugs/1914568

[Impact]
Enable the Android modules ASHMEM and BINDER_IPC in the Azure kernel.

[Fix]
See patch 1/1 for config changes. Set CONFIG_ANDROID=y, CONFIG_ASHMEM=m, CONFIG_BINDER_IPC=m

[Test Case]
1. Installed the kernel deb, linux-modules, and linux-modules-extra.
2. Booted the test kernel.
3. sudo modprobe ashmem_linux
   Checked dmesg for errors
4. sudo modprobe binder_ipc_linux
   Checked dmesg for errors.

[Where problems could occur]
Though the Android subsystem is in staging, enabling ANDROID=y appears to be a standalone operation.
There should be no impact until the Android modules are manually installed.
