sdhci-tegra provides a get_ro method, which overrides the checking
of the write protect bit in the PRESENT_STATE register in sdhci.c:
if (host->flags & SDHCI_DEVICE_DEAD)
is_readonly = 0;
else if (host->ops->get_ro)
is_readonly = host->ops->get_ro(host);
else
is_readonly = !(sdhci_readl(host, SDHCI_PRESENT_STATE)
& SDHCI_WRITE_PROTECT);
This means it's pointless detecting accesses to this register and
manually setting the SDHCI_WRITE_PROTECT as it has no effect.
This means that the whole of tegra_sdhci_readl() can be removed and
we can use the builtin sdhci readl functionality here.
