[PATCH] ARM: at91: sam9_smc: remove redundant SAMA5D2 check

[Alexander Shiyan]

The SAMA5D2 SoC uses a different SMC driver implementation (located in
drivers/mfd/atmel-smc.c) and doesn't utilize this low-level sam9_smc
driver. The check for AT91_SOC_SAMA5D2 in the read mode function is
therefore redundant and can be safely removed.

This cleanup eliminates dead code and improves maintainability by
removing an unused codepath. No functional changes are introduced.
