tlmi_priv.pwd_admin->password is an array (not a pointer), so the correct
way to check for the password being set is to check for
tlmi_priv.pwd_admin->password[0] != 0.
For the second check, replace the check with checking that auth_str is
set instead.

The dell-wmi-sysman and think-lmi kernel modules both have a global
struct class *fw_attr_class variable, leading to the following compile
errors when both are builtin:
ld: drivers/platform/x86/think-lmi.o:(.bss+0x0): multiple definition of `fw_attr_class'; drivers/platform/x86/dell/dell-wmi-sysman/sysman.o:(.bss+0x0): first defined here
In both cases the variable is only used in the file where it is declared.
Make both declarations static to avoid the linker error.

tlmi_pwd_setting
The struct tlmi_pwd_setting display_name member is initialized,
but never read. Remove it and the TLMI_PWDTYPE_MAXLEN define.
While at it also remove some other unused [MAX]LEN defines.

For Lenovo platforms that support a WMI interface to the BIOS add
support, using the firmware-attributes class, to allow users to access
and modify various BIOS related settings.
