[RESEND PATCH v5 0/5] arm: Fix DEBUG_LL for multi-platform kernels (without PL01X)

[Daniel Thompson]

This patchset removes some single-platform compatibility tricks related
to DEBUG_LL and, as a result, allows multi_v7_defconfig derived builds
to enable DEBUG_LL without forcibly selecting of the PL01X's DEBUG_LL
implementation (which doesn't work on some platforms).

- Tidy a couple of existing defconfig's so they continue to issue
  DEBUG_LL messages to PL01X when the subsequent changes come along.
- Limit DEBUG_LL_UART_NONE to platforms that support it
- Fix a potential build problem on EP93XX
- Get rid of the compatibility code that causes us to forcibly enable
  DEBUG_UART_PL01X 

Daniel Thompson (5):
  ARM: versatile: Enable DEBUG_LL_UART_PL01X
  ARM: ep93xx: Enable DEBUG_LL_UART_PL01X
  ARM: Conceal DEBUG_LL_UART_NONE from unsupported platforms
  arm: Seperate DEBUG_UART_PHYS from DEBUG_LL on EP93XX
  arm: Fix DEBUG_LL for multi-platform kernels (without PL01X)
