[PATCH] drivers/firmware: make efi/esrt.c driver explicitly non-modular

[Paul Gortmaker]

The Kconfig for this driver is currently hidden with:

config EFI_ESRT
        bool

...meaning that it currently is not being built as a module by anyone.
Lets remove the modular code that is essentially orphaned, so that
when reading the driver there is no doubt it is builtin-only.

Since module_init translates to device_initcall in the non-modular
case, the init ordering remains unchanged with this commit.

We leave some tags like MODULE_AUTHOR for documentation purposes.

We don't replace module.h with init.h since the file already has that.

Looks good to me. I know Peter is on vacation right now, so I'm still
expecting a response from him. In the meantime, I'll queue this up in
the EFI 'next' branch. Thanks!

Thanks Peter. May I add your ACK?
