platform/x86: thinkpad_acpi: Fix errors reading battery thresholds
Check whether the battery supports the relevant charge threshold before
reading the value to silence these errors:
thinkpad_acpi: acpi_evalf(BCTG, dd, ...) failed: AE_NOT_FOUND
ACPI: \_SB_.PCI0.LPC_.EC__.HKEY: BCTG: evaluate failed
thinkpad_acpi: acpi_evalf(BCSG, dd, ...) failed: AE_NOT_FOUND
ACPI: \_SB_.PCI0.LPC_.EC__.HKEY: BCSG: evaluate failed
when reading the charge thresholds via sysfs on platforms that do not
support them such as the ThinkPad T400.
Fixes: 2801b9683f74 ("thinkpad_acpi: Add support for battery thresholds")
Closes: https://bugzilla.kernel.org/show_bug.cgi?id=202619
