[PATCH] staging: greybus: audio_manager_module: make envp array static const

[Chang Junzheng <guagua210311@qq.com>]

From: Chang Junzheng <guagua210311@outlook.com>

The envp array in send_add_uevent() function is declared as a non-const
local array, which triggers the following checkpatch.pl warning:

WARNING: char * array declaration might be better as static const

Change the declaration to 'static const char * const' to improve code
safety by making the array read-only and allow for better compiler
optimization. This follows the kernel coding style recommendations.
