[PATCH v2] arm: Fix DEBUG_LL for multi-platform kernels (without PL01X)

When building a multi_v7_defconfig kernel it is not possible to configure
DEBUG_LL to use any serial device except a ARM Primecell PL01X, or more
accurately and worse, it is possible to configure a different serial
device but KConfig does not honour this request.

This happens because DEBUG_UART_PL01X, which is intended to provide some
kind of compatibility with single platform builds, spuriously depends upon
ARCH_SPEAR13XX (and similar SPEAr options).

Problem is fixed by removing problematic dependancies.
