manual pages of acpi_* drivers

[Rong-en Fan]

Hi,

Some time ago, we build all acpi_* on all platforms,
However, manual pages are still built only on i386.
I think they should be moved to arch-independent
directory.

In src/share/man/man4/man4.i386:

acpi_aiboost.4,v    acpi_fujitsu.4,v    acpi_panasonic.4,v  acpi_toshiba.4,v
acpi_asus.4,v       acpi_ibm.4,v        acpi_sony.4,v

should be moved to src/share/man/man4, then
apply

http://people.freebsd.org/~rafan/acpi.man.diff

to hook them to arch-independent build.
