soc/tegra: fuse: Refactor resource mapping
To prepare for adding ACPI support to the tegra-apbmisc driver, relocate the code responsible for mapping memory resources from the function ‘tegra_init_apbmisc’ to the function ‘tegra_init_apbmisc_resources.’ This adjustment will allow the code to be shared between ‘tegra_init_apbmisc’ and the upcoming ‘tegra_acpi_init_apbmisc’ function.
