[2/9] kernel: change CONFIG_HW_RANDOM default to y

Many devices do not have hardware random number generators.  Yet
more do than don't, and they are becoming more common.

Why isn't this migrating upwards into target/linux/generic/config-5.15 and target/linux/generic/config-5.10 in that case?

And for the platforms where it was turned off, like target/linux/armvirt/32/config-5.15, why isn't that staying unchanged?

I'm guessing you're unaware of a subtlety of how the .config system
actually works.  Take a second look, some handy examples:

armvirt/32 previously had it off and it is still off.  armvirt/64
previously had it on and it is still on.

Most similar systems would treat "# <option> is not set" as undefined or
no preference (use the default value).  The Linux kernel system treats
this as "no" due to the history of the system.  Yet it also honors "n"
as "no".

I tend to prefer "n" as it hints at a value being deliberately chosen,
instead of being left unset/undefined.

Enumerating it explicitly saves me having to get into the kernel sources and grep Config files for a default.

Please use the same syntax as in the rest of the file. Occasionally 
kconfig.pl will be used to add entries or re-sort the file, and 
mis-matching the existing style will cause spurious extra changes in 
that case.
Also, please fix your mail server, I get bounces when sending to you.
