acpigen: Add printf-like function for debug string
Generate formatted string and ACPI code to print debug string.
For example (with pcie_rp = 1):
acpigen_write_debug_sprintf("calling _ON for RP: %u", pcie_rp);
generates the following ACPI code:
Debug = "calling _ON for RP: 1"
With this new function, the following functions are not needed anymore
and therefore are removed by this patch.
- acpigen_concatenate_string_string()
- acpigen_concatenate_string_int()
- acpigen_write_debug_concatenate_string_string()
- acpigen_write_debug_concatenate_string_int()
BRANCH=firmware-brya-14505.B
TEST=Add above functions in the acpigen code and check the generated
SSDT table after OS boot. Check the debug messages is in the
kernel log when /sys/modules/acpi/parameters/aml_debug_output is
set to '1'.
