[PATCH 6.0 026/157] LoongArch: Combine acpi_boot_table_init() and acpi_boot_init()

From: Huacai Chen <chenhuacai@loongson.cn>

[ Upstream commit 538eafc6deae12fbac5f277b89aa139b812bca49 ]

Combine acpi_boot_table_init() and acpi_boot_init() since they are very
simple, and we don't need to check the return value of acpi_boot_init().
