Update several Anacapa SGPIO line names to match the existing platform hardware design and the signal names consumed by userspace monitoring. The previous names did not match the actual Anacapa SGPIO usage. Some lines were named as CPU or CPU power-good signals, but they are wired and used on Anacapa for EDSFF presence, EDSFF power-good, boot EDSFF presence, and thermal-trip assertion monitoring. Correct the mappings as follows: PWRGD_PVDDCR_SOC_P0 -> L_PRSNT_EDSFF0_N PWRGD_PVDDIO_P0 -> L_PRSNT_EDSFF1_N PWRGD_PVDDIO_MEM_S3_P0 -> R_PRSNT_EDSFF2_N PWRGD_CHMP_CPU0_FPGA -> R_PRSNT_EDSFF3_N PWRGD_CHIL_CPU0_FPGA -> HPM_EDSFF_PG EAM2_CPU_MOD_PWR_GD_R -> PRSNT_EDSFF_BOOT_N CPU0_SP7R1 -> L_EDSFF0_PG CPU0_SP7R2 -> L_EDSFF1_PG CPU0_SP7R3 -> R_EDSFF2_PG CPU0_SP7R4 -> R_EDSFF3_PG HPM_AMC_THERMTRIP_R_L -> AMC_THERMTRIP_ASSERT FM_CPU0_THERMTRIP_N -> CPU_THERMTRIP_ASSERT The left-side EDSFF slots are numbered as EDSFF0 and EDSFF1 to match the platform slot numbering used by userspace. The thermtrip names are also updated to describe the asserted condition monitored by userspace instead of the raw active-low signal names. This is a naming correction for the existing Anacapa hardware design. There is no new board revision or underlying hardware change involved.
