power: reset: at91-poweroff: Fix module autoload 



If the driver is built as a module, autoload won't work because the module
alias information is not filled. So user-space can't match the registered
device with the corresponding module.

Export the module alias information using the MODULE_DEVICE_TABLE() macro.

Before this patch:

$ modinfo drivers/power/reset/at91-poweroff.ko | grep alias
$

After this patch:

$ modinfo drivers/power/reset/at91-poweroff.ko | grep alias
alias:          of:N*T*Catmel,at91sam9x5-shdwcC*
alias:          of:N*T*Catmel,at91sam9x5-shdwc
alias:          of:N*T*Catmel,at91sam9rl-shdwcC*
alias:          of:N*T*Catmel,at91sam9rl-shdwc
alias:          of:N*T*Catmel,at91sam9260-shdwcC*
