[PATCH] hw/sd/pxa2xx_mmci: Disable reentrancy detection

[Guenter Roeck]

All tests using pxa2xx_mmc to access mmc cards on pxa2xx platforms
such as borzoi fail starting with commit a2e1753b80 ("memory: prevent
dma-reentracy issues"). Disable reentrancy guard to fix the problem.

Fixes: a2e1753b80 ("memory: prevent dma-reentracy issues")
