bcm27xx: additional kernel optimizations on bcm2712

Further trim leftover hardware support inherited from other SoCs
and reference designs that don't apply to bcm2712: Broadcom
set-top-box (BRCMSTB/BCMA) support, and unrelated third-party
silicon (Microchip PHY/PCIe host, SMSC PHY, PLDA PCIe host,
Cadence MACB's PCI wrapper).

Keep CONFIG_ARCH_BRCMSTB and CONFIG_RTC_DRV_RPI enabled: the CM5's
firmware-backed RTC depends on this switch despite being unrelated
to actual set-top-box hardware. CONFIG_SOC_BRCMSTB/SOC_BUS/GLOB
also remain, pulled in via PHY_BRCM_USB's dependency chain.
