Subject: [PATCH v2] ARM: imx: limit errata selection to Cortex-A9 based designs

From: Stefan Agner <[email protected]>

The two erratas 754322 and 775420 are Cortex-A9 specific. The i.MX 6UL
SoCs include a Cortex-A7 CPU and hence do not need this erratas enabeld.
This patch moves the errata selection from the family Kconfig symbol to
the SoC specifc Kconfig symbols where a Cortex-A9 is used.
